MLP Spike's sprites

On december the 10th, there is an episode from My little Pony: Friendship is Magic I really want to see! It's about a macro Spike and since I love giants, I needed to draw him! >=3

Well... I did the regular sprites with walking movements. I added alternatives colors to show my Spike form as well. ^^

And to finish... Well... The macro one... I manage to do bottom body but the head... I'm having troubles then. If anyone can help me to fix that, that will be cool and helpful. And remember I'm ready to do collabs, and so... I'm ready to share thoses sprites (give credits of course).

So... Anypony can help me to fix the macro one please?

Update on 12/03/11: Macro Spike redone with Thunder-Felix and GollyGosh (on FA). Thanks guys to help me to fix the macro one. He's better than the one I did before. ^^

Update on 12/11/12: Macro Spike redone once again. I mostly redid the head. Looks much better than before now.
