I've wanted to learn how to paint in Photoshop for awhile now. I love Adobe illustrator but I wanted to have a hand drawn/painterly look to my artwork that I just couldn't get with Illustrator. I tried watching videos on Youtube and playing around with Photoshop myself, but I never had very good results.
Here is one of my first attempts at illustrating in Photoshop. It's not horrible but it's not the greatest.
After I drew this bunny I bought the Kyle Webster brushes Mega pack and they helped tremendously. There were so many brushes though and it has taken me awhile to just get to know even a quarter of them. With his brushes I definitely saw an improvement.
I was still afraid to draw without using a sketched outline. The turning point for me was after I took Stephanie Fizer Coleman's Photoshop for Illustrators: the Basics class. I've worked with Photoshop for years with photos but using it as an illustrator is completely different. She really breaks it down and explains how she sets up an illustration from start to finish. What her favorite brushes are and how she chooses her color palette. So informational. After the class I decided to jump all in and do my next illustration with Photoshop only. I did sketch it out in Photoshop first but not with pencil and paper. It wasn't a terrible mess and I'm sure I can improve on it eventually but to me it represents a huge step in my artistic progression.
