I like shiny Mew *.* Your style changed A LOT though. You're making black lineart, and it's cleaner and thinner.
I have something to say about the coloring, it seems you're using a shading tool to color it, I've seen it on your most recent OCs too, and that will possibly hold you back. If you practisedPRACTISEDpractised, you would improve on shading, choosing the right colors and stuff. If you keep using a shading tool, you won't have to work on it and you'll see regress instead of progress.
The eyes are simply beautiful, that I must say. You spent a big deal of time on them and the piercing effect on them is beautiful!
