I've also got a question about something I noticed while drawing this. Or rather, I'm having a problem I can't understand.
Whenever I see other peoples art I think: I want to draw like that! So I open up a new image and try to color like them. But it doesn't work. In the end, I go back to how I usually color and I'm actually okay with the result. Why? Can anyone explain this?
Maybe for you doing other coloring styles does something similar to what turning an image upside down would do. It lets you see the flaws you've become comfortable with and can't see in a normal situation. Since your main goal in making art is to make something that looks good, you revert to the style you're comfortable with, the one you can't see the flaws in and can be happy with. If you want to make learning your new main goal and get past it you'll have to be able to let yourself make ugly art.
That's a really beautiful picture~ The movement in the hair is especially nice.
Like Sharm said, your brain is likely just rejecting the strangeness of something different and something you aren't quite 'good' at yet, so it slips back into the happy comfort zone. You have to push back your brain's relationship with safety if you really want to experiment with new styles! It's going to be jarring and strange and get a lot of "nope' reactions from your guy - but just ignore that best you can.
Good lord this is taking forever, I'm not even out of the opening really and I've still got hours worth of work to do before I get to the main gameplay loop. Orphan of Time will probably be done some time next year, If I'm lucky.
