Thanks for your critique, LachieD.
I will try to fix the body of the bird to look more featherish, as you said.

Thanks for your critique, Mr.Fahrenheit.
I will replace that for a lance, you are right that is a lance is more distinguishable than a sword. My thought was that when on a flying creature, one could do nothing with a standard sword on hand except throw it at the general direction of the enemies and go home... haha.

Thanks AlabasterJazz!
I found that feathers and wings are so hard to do in pixel art! I will look foward to redo that.

I think it's the wings and eagle claws that throw this off for me... the wings need to look more "feathery" especialy the large primary feathers, the claws seems a little too bulky and unnaturally stiff.  Overall I'm impressed, but with a little tweaking this has the potential to be really great

 I think its supposed to be a lance, in which case it should be longer so to be easily distinguised from a large sword.

Looks a bit akward. I do like the bird's heads and the bottom leopard part, althought it would be nice to se a more seamless transition between the bird and the leopart part. Perhaps if the bird part looked more featherish. 

I also think the sword is too big.
