There's so much I love about your art style it's hard to choose points in each piece. Here I'd have to say excellent habitat choice for each.

I am such a huge Wartortle fan, that middle one really really got me.
Got me right in the feeling-place.

A great and detailed image overall, but I love Charizard's smirk in particular.

This is unbelievably epic and probably your best piece! You're so amazingly talented and creative!

These are amazing!!!!!!!!!!!!!
This is quite the artistic take on poke'mon!!!!!!!!
