A. I liked C at first, but the N started to look weird and the ostrich looks like a duck. The block idea is cool, though.

The ostrich on A isn't super obvious other than the legs. Those are great. The neck and head need to be more ostrichy.  

 Great feedback. Most like C, but same feedback around the N.
Thinking to go with C, fix the N and B, and flatten the nostrich 

 I like B on the left but they’re all cool 

 My fav is B also, but the majority likes C.. Gonna ask @awayuki to keep C and make it look more like B, with an ostrich of A 🤣🤣 

 Great idea!
