Oh these are so pretty! I love Ivysaur and Venusaur, details and texture looks really good. It looks like you used a little pit different style on Bulbasaur, did you? This would be awesome as a t-shirt print.
Nice! I especially love how dynamic bulbasaur's pose is. ;u; And how powerful both ivysaur and venasaur look with those stances and attacks and everything. Also how they got more and more detailed as they evolved haha. :b
I drew the first 151 Pokemon before, and was it ever a challenge! Good luck and hurrah for your awesome art!
