I'm going to be 100% honest, if you wanna get better then you need practice. I checked your profile and your drawings, and the drawing aren't that good. And lines are pretty sloppy and the coloring is..eh. I'm not saying that to be mean at all btw, I think you just need more practice. I've been drawing for 7 years and I'm not that popular here, just practice more and you'll do great. Trust me.
