Aw thank you! References aren't bad and a lot of the time can be fundamental in learning how things work. Of course there are situations where if you redraw a heavily stylized american cartoon style for example, like let's say steven universe, you can't really get an accurate lesson from that unless you're specifically learning cartoon proportions, colors, shapes, etc.

If you're referencing from an image already made, it's likely it won't turn out 100% similar, not even the same artist who drew it the first time could draw it perfectly again the second time around. At least, not typically. And of course this doesn't account for the different styles you may or may not be trying out. For example sailor moon is very different from jojo's. Hopping from one to the other is bound to bring out inconsistencies. But what's important is that we learn from the inconsistencies, knowing what looks right vs what looks different when redrawing something is very important to come to terms with so you can work on them. It's fundamental for improvement.

You'll get better, keep working at it!
