I was going to put this in the drawfriend, but It's not really a drawing is it? We have seen tons of Gmod ponies which were based on the old KP-Shaddowsquirrel models, but these designs are totally different, and bring out a lot of features those don't really touch upon. Transitioning ponies into a 3D space has always been a challenge, and while the source ponies are useful, it's neat to see a different perspective. Hashbro over on Deviant Art has spent the past year creating models for Twilight, Octavia, Scratch, Lyra, Pinkamena, and now Derpy. A few of them are actually available on Shapeways as 3D printed versions.
Head on down below the break for links to everything, or just hit up his gallery and dig on your own!
Note: (Hashrbo, not Hasbro, these are fan made)
