Ello, This is my first critique so... Before I say anything I'd like to comment on how fabulous Midna looks!
Midna: I think you could have spread to hair further across the helmet so it won't look like such a tuft. Also, if you put more tones in the hair it'd look more 3-d and if she was a bit "glowier".
Link Wolf: Okay, this pose is really quite unnatural, but you pulled it off well. The front and back legs should be spread a bit further away. The paws are all in the same, forward position, and the hind ones should be a bit more out-turned. The upper half of the chest is the real killer here, It's WWWAAAYY to big, he looks a bit inflated. The green needs too blend a bit more too... That's it for linky
Sword: The only flaw here is the blade's a bit wide, that's all.
Over-all, I feel like a real snobby meaner for dishing out... This is wicked though
