I apologize a bit for that as I was slightly annoyed at the time. However, there are a few complaints I still stand by. I'll try to be more constructive in pinpointing exactly what needs improvement namely:
Greninja's eye is comically big.
Amaura and Auroros's line work makes it seem grainy at %100 zoom.
Both Meowstic's blue seems like it leans too heavily towards it's dream world art.
Sylveon still looks slightly... off. I can't pinpoint why... maybe it's the eyes?
Floette, Flabebe, Sligoo, and Goomy and Diancie
do not follow Chaos Rush's rules for sprite sizes. They all need to be sized down.
Hoopa's horns are way too big.
Hoopa-Unbound needs a repose, as it also doesn't follow the size rules, only backwards.
I will work on some of these myself, and hopefully you will see where I'm coming from.
About capylus' sprites... I think his mega Lopunny is pretty good. I think that of the three, it's the most salvageable.
EDIT: I've edited capylus' mega Lopunny sprite. I didn't do much, aside from tinkering with the shading.

Also, here's that Sylveon W/ shiny pallet:
