I've experimented a lot this last year and picked up some ways to work digitally by some very talented artists. I thought I would share a little project I'm workin on with RethinkDB, and give a play by play.
I usually come up with some ideas, knowing that many of them wont work at all, and all of them will have to change. I have this awesome photoshop brush package that has the most amazing textures made by Kyle. Kyle is legit: https://gumroad.com/kyletwebster
I like to use texture and different brushes to experiment with shapes and composition, just like I would with real media. The more variety you have within your tool kit, the more rich and varied your work will look- always a good thing.
Then I do a color study or even start the final illustration. The key here, though, is to stay loose and not go into too much detail. If it's rejected then I don't want to be attached to it or spend too much time on it. "Just have fun," I remind myself.
I'm still working on the finished illustration. It might go through several iterations, so I'll post more soon. Until then, check out the brush package, get yo'self some new sketch materials if you can, and share your progress on a piece. I'd love to see- I tell you that!
