What should I do to understand complicated artistic concepts better?

I suck at art, not only making it, but understanding it too, ant tip for me?

I am not a pro in art and design but i have been drawing as a hobby since childhood.
So to better your art try to first learn something about what is to feel any animate or inanimate objects with your heart and to do that you have to have a clear concept of what art is. Because Art is connected with beauty of your heart. So try to read some books first like of Anatomy for the Artist by Sarah Simblet, Drawing People by Barbara Bradley etc . And then take it a one step a time. My believe is 'Understanding is essential in any subject of learning' . My suggestion is also journey to the monumental sites , archaeological sites , best built church or building , mountain or spend some time in parks if you have time. They will always be your first teacher in Understanding your desire.

make it a point to understand the fundamentals and theories about art, if you dont understand the building blocks or general concepts it will always be hard to put together something that feels complete because you are missing important aspects

research about composition, color theory and harmony, perspective and space, gestalt principals, balance, rhythm, grids, etc.

googling "design principles" and "elements of design" may help

I didn't take drawing """seriously""" until middle school, but I can't recommend enough the benefits of copying other drawings. NOT posting them and claiming them as your own, just for practice. People will tell you that you just "gotta find your own style" and that's a lie, you gotta find some other style that works for you and make it your own with enough practice.

I love the Avatar style of drawing and animating humans, so the most helpful thing for me was watching some of the show, taking screen shots, and just re-drawing those screen shots until I got a better idea of how faces were shaped, where the eyes sat in relation to the nose, how things look from different angles and expressions. In terms of animals, I copied a lot of Disney stuff. But Avatar and Disney are their own things, so there comes a point with enough practice where you can start visualizing poses and figures without finding an exact screen shot of what you're thinking of, and you might make stylistic changes that just look better to you and fit the scene better. Boom, now you have your "own style."

It really comes down to practice. You can start with references, but practicing is what really makes a difference. I recommend something like Inktober or some other drawing challenge that has you drawing daily, and you'll be able to see change throughout the month/duration of the challenge.

Hopefully this'll help you get off the ground!

Depends on what medium you want to do, but youtube is your best friend for teaching yourself. Play with concepts and let the ideas flow.

suck at making ur own art? trying making master copies

The best way is try to replicate it.
You will push yourself to learn the techniques and styles to achieve it.
It will make you better in understanding the design / art too and how much work goes into it.

I'll recommend you to start simple, like drawing objects that are easy and level up by watching tips. tricks and tutorial that are available on youtube and tumblr

It depends on what you're trying to achieve. When friends want to get into drawing/digital art/painting, I try to tell them to practice drawing from life. Still life, photos, yourself in a mirror. Learning how anatomy works in the real world is key to understanding how it can work in a more cartoon style, if that's what you'd like to go for. I also tell beginners that copying is fine, as long as you're not trying to pass it off as original work. Find an artist whose style you admire and would like to emulate, and the more people you want to emulate the better, and try to eyeball pieces of theirs that you enjoy, to get a feel for how they may have done it. Combine the aspects of the styles that you particularly like. It might not look good in the beginning, but as you go and improve, it gets better.

Use references! My art looked like garbage when I was trying to pull everything out of memory. As you reference things more, if it's a common theme in your art you may not need as much reference anymore, but until then references will help you so much! Any time I come across an image online and I think "oh I love the fold in that cloth at his elbow" or "wow that's a cool angle on that animal's face" or "that is amazing lighting reference" I save it. I have so many reference folders across so many devices! And it's the same for color schemes. Familiarize yourself with the color wheel and he ways colors can be combined, and with concepts like tint and hue, but if you have a hard time with it in the beginning there's no shame in mimicking the color pallets of other artists to learn how it works.

Just take it one step at a time. Sketching is a good place to start, then you can dip you toes into whatever type of art you think you might be interested in! It's best not to overthink it. We all start from square one.
