I just got a question in my inbox about tips and tricks to improve your art, and I figured I'd share my answer with everyone - I hope someone finds it helpful. I don't fancy myself a teacher but I think I can distill the recipe for my own improvement down to these basic points.
I can't help much without seeing your work, but I'll share my very own basic thoughts for improvement no matter your skill level.
1 - Join an art community, and get involved. Having people around who share interests in art, are in the same boat, can critique you and ask for feedback is super fucking important. Make sure you hop on the Art School Discord, you make a forum post here on Cubebrush, and participate everywhere you go. It's a lonely journey, so find friends.
2 - Copy stuff. A lot. Find your top 3 favorite artists and copy their work on a regular basis. This is your only homework, and it's the highway to improvement. Check your homework yourself by overlapping the original and your version in Photoshop and noting where you made mistakes. Post these copies online by calling them a STUDY because that's what they are. Do not pass this off as your own work, it's a STUDY of a master. Apply the feedback you're given.
3 - Watch Youtube videos from good teachers. Chances are, unless you've been painting for years and years, that you know very little about certain very fundamental subjects and techniques that might come in handy when painting. Youtube teachers are free, and their content is pure gold. I recommend Sinix Design, Proko, Marco Bucci, Marc Brunet, ModernDayJames, but there are many more.
Do a little bit of this every day. Good luck! ^^
