any insane ideas for designing?

If you go on Pinterest and look up futuristic Y2K aesthetic you might find some pretty cool stuff.

Inspiration comes from nowhere, in any case it happens to me, so in order not to wait for long inspiration, I just look at royalty free images and get inspired by textures, photos and colors, and also use these photos for my own purposes in the future.

Honestly it really depends on what you want to do, give us more info maybe

If you can give us more info on what you like, or what you do not like, we may help you... but just to say something that may lead you to some place: "a cold water jar"

try making it hyper pop themed

for me the inspiration comes from the artistic / design culture reflected through your subject and then with the use of your skills. Several ideas arrive at this time

use Pinterest for latest design ideas

try using colors that normally don't go together
