Improve to a new level

Hello. What are the best photoshop courses for someone who wants to improve their design to a more professional level?

i wouldnt recommend courses rather tutorials for specific things you want to create and just pick up the essentials from there thats how i learnt!
good luck!

I also would recommend you courses you get much deeper into the tools and function of a Software. Also you don't only learn how to do a effect, you also learn how to get "an eye for graphic design". Invest the time into courses you will not regarding it.
