The Steel and Dragon eveeloutions are the best out of the seven I'd say, with a close second for the ice one.
Poison- Just looks odd to me. The posistion justs weirds me out, but a little bit of touching up on the body and head would work. Looks as though there's no neck.
Grass- Great, I love the blooms on the ears. The Meganium flower is overused for Grass-Eveelutions, though.
Ice- Good, but still an awful lot of Espeon-ism in there.
Steel- The design, basically, is a great idea. Maybe something other than Dragonair wings though... and maybe a ankylasaur-style tail.
Dragon- I love the mouth! It just makes it look...more dragon esqe, maybe some teeth and it'd be perfect.
Bird- The face is too sideways for my liking, a bit more angled and it'd be great.
Bug- Okay, A bit bright. The tail needs definte darkening up.
