A recent Pony design I can't use (yet)

Recently I have been spending so much time on marketing that I haven't really created very much at all. I did create a cute pink pony for the Animatastic range but when completed I realised it bore a striking resemblance to the 'My Little Pony' products. After all the work creating it I really didn't want to simply abandon it so I contacted Hasbro, the makers of 'My Little Pony' and am currently waiting and hoping to hear back from them on whether or not they would consider the design to be copyright infringement.

While it does look a lot like the MLP that I had as a child, it was genuinely a coincidence that it turned out that way. When I had that thought I immediately googled MLP to compare and can see a few little differences. Firstly, my design has a shaded muzzle - woohoo, big deal huh? lol. Then there is the shape of the legs; the MLP legs don't taper as a real animal's would, instead they get broader all the way down. Finally, the MLPs don't have hooves wheres my design does. Having said that, I am holding off on using the design for now. Hopefully Hasbro will respond soon.
