Mos-Quitoxe
I really liked the innovation of these two designs above all of the others. They both do the evolution in a cool way that I appreciate as an individual, but which reminisce of different real Pokemon. paint keeps with the humanshape structure, but totally in a unique style. I like it because it's angsty and has a lot of emotion in a very unique way. Mos-Quitoxe's is cool in that it's very Larvesta > Volcarona, but I think it's second to paint's because it still reminds me too much of Joltik and a Bug-type. Mos really never addressed that feedback, so I just can't place it on the top of my list. The other ones were cool and all, but these two stood out so far above the rest that I put them in a tier unto themselves.
Good luck!
