Yup, I use to get a lot of crap the way I drew Sapphirus in the past and the rest of my art, originally her hair was blue, then I made it red, from a temp fandom thing, then back to blue with light Blue streaks again after.
Looks like I proved those idiots wrong. Anyone can improve, takes time. You got ppl who think you're suppose to improve altogether in one day. Some take longer than others, everyone has a pace of improving.
