Just practice and draw all the time. But only draw what you want. for me, when it becomes a chore it makes me lose my ability and I dont want to draw anymore. So I have to find things that I know i'll enjoy xD
Yes! I'm always challenging myself daily to draw something I haven't drawn before. I can't say there isn't anything I don't want to draw, since because of my limited exposure, drawing anything brings me some amount of joy. Just mentioning something will bring about a flood of ideas that overwhelm my every sense! I love to draw so much its hard to just pick one thing!
