Drawing characters easy.
Drawing backgrounds the bane of my existence.
Drawing backgrounds + characters...makes me want to jump off a bridge. for real something I'm TRYING to do. Honestly, the only want to get around that is to practice. That has to be the hardest thing with comic making. But I shall prevail!
And tips to avoid artist block, don't burn yourself out. Don't GO GO GO. Take a break and not do art for a while. You need to find a balance and a rhythm. I also take time to look at other artist work, watch things that inspire me (animation/movies/books/tutorials), and I also binge on music. Sometimes if I have a few projects going (example: I have a freelance graphic job, freelance illo, and my own comic) I switch between projects, 1 hour here, 1 hour there, and 1 hour Not Doing and on FB or something or going out with my friends.
