It is a bathorse. Nothing weird there. Put batwings and dragontail on a pegasus mold and you'll have a fabulous thing straight away! I did that with some Breyer horses and they look spiffy! ;-D
This is adorable! I love it! I have so many of these sorts of things (bat unicorns and bird unicorns) that I draw a lot because they look so silly. I read a book series by Stanton I think where a "demon" had a huge horse head on a small bird body and the author really stressed how awkward it was. BUT YOU MADE A BAT HORSE LOOK NATURAL! OMG!
