Draw an exhausted pony/Draw a pony burning out.
(wheel-spins is another word for Burnouts)
This could fit either theme, but the point here is that Vinyl tried to gallop a little too fast and tripped, skidded and kicked up some dust. Or maybe some smoke if she was really going that fast (ouch!).
This one was done just a bit too quickly, I felt like a break tonight, so there wasn't a lot of time or effort poured in to this.
How do you anatomy?
Edit: Didn't realise last night, but that joint is backwards. I believe I must've been thinking about the lower joints as a foreleg and not a hindleg. Or maybe she twisted it... really freaking badly. TT___TT WHOOPS! Will probably fix after the ATG.
