Though it's not like Sonic has room to complain.
One thing that always made me hesitant to draw a Sonic/MLP:FiM crossover was how the ponies should be rendered--as-is or as Mobians (I had a different view back then, but nowadays I don't like seeing Mobians next to non-Mobians unless one has been tweaked to fit the style of the other). For this pic I decided to see how a Mobian and a pony would look side-by-side; not sure about the result, but I guess the pic itself is cute.
Not really meant to have romantic implications (though you can see it that way as long as you don't yell at me for it); just Dashie being a butt.
(As for the highlights on Sonic, darkening them with teal worked fine on paper but not so much after running it through the scanner. Rrgh.)
