Haha, I tend to be that way too~ Though sometimes after I've drawn with a ref long enough, I can do it from memory... and then I tend to draw it the same exact way for all of ever until I finally get comfortable enough to change up poses and expressions and such. XD
Your Masquerain is definitely off, though that might just be because GameFreak's is demented (are those wings or antennae, and are those wings or feet, and how the heck does it even fly?). I started challenging myself to draw random Pokemon from references, and Masquerain drove me kind of crazy.
I know it's off. My memory isn't perfect. Maquerain is one of those Pokemon I never payed any attention to and because of its randomness I had no idea what it looked like. Masquerain makes absolutely no sense.
