You should be proud as hell of this one, amigo. Very unlike all of your other arts (which isn't a bad thing at all, by the by the by) Work more like this and you'll be a Blastoise.
Note: I've decided your art has gone through three stages. The beginning, with vectors and your first arts being Squirtle. Currently you're in your Wartortle phase. I feel like this Fluttershy is the first step at you becoming the big bad Blastoise you've always wanted to be. (I could be way off)
