Love the Typhlosian/Nidoqueen one. It's just one part of an ongoing series from that artist, apparently - and the whole thing was commissioned by Graedius, who appears in some of the pictures as Typhlosian's trainer. It's not finished yet, but they're up to Part 4 so far.

Graedius also recently had this commission done as well (available on both FurAffinity and Inkbunny):
