Is there a bit of Gurren Lagann in that design? :o
Like Albinoloon though, I'm not sure how I feel about it. I felt like the head on top of the last one really added a lot to the design.
I can see the centaur thing working out really well, I see that the horse part seems to be made out of some sort of fire/ectoplasm stuff, and I think if you ran that through the suit of armor and put like... a ghostly head coming out of the armor it'd look really nice.
As for my fakemon, it's a mix of a few things, but mostly a Thorny Devil, a Velociraptor, and for a bit of a twist, an anteater.
