I had a few older sketches than these but I think the fun starts here.
This sketch was made during the Bronies NL meet #9. Most of this stuff is still practice, so there's plenty of mistakes to be made.
The flying thingy is a miniature Juggernaut from the Marathon games.
Also, Pinkie with a slinkie neck. A bit creepy, but I assure you my intentions were purely silly.
