To make it easier, the artist(s) are listed right next to the links and if they're anyone except "Noscium" it's probable they're different- not necessarily better, but different.
EDIT:
Personally at a quick glance, I think this Florges looks better, as does Avalugg and I think maybe Aromatisse and Slurpuff (maybe?).
The Aegislash is at least colored properly.
Pangoro is... strange- the facial expression seems better but I don't know about the rest.
Dendenne is much better, but the angle is odd.
Yveltal is better shaded, if that matters. Strike that actually I don't know if it's better, after a second look.
