Hello Paradox56! Welcome to our herd! Definitely an interesting cutie mark. Is your OC the equivalent of MC Escher? Or does he just do that sort of stuff naturally, kind of like Pinkie Pie? As for best pony, I loved RD when I first started, but I've wandered through all the ponies as my favorites. Right now, Rarity has a very slight edge, and Twilight comes in a close second. Well, let's get to a posting ponies, listening to EPR, and making some new friends, and having fun! Those things aren't just going to happen by themselves, y'know!
