Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I voted for Doug in the end, although I loved all three sprites. The thing that drew me in about Doug's and Cartoons' sprites in particular is the bulky appearance of them. I can see both of them easily shrugging off CBTar Stone Edges and wrestling him down to the ground bellowing YARRRGH. I ended up picking Doug's in the end because I felt he had the best hook out of all the sprites.
I chose Doug's sprite mainly for the shiny, which just looks awesome. Cartoons! front post just looks so much more ready-to-rumble and alive for me. Close call. If they could somehow be combined.. :)
Cartoons! Vote based on the stance and the colouring. If you don't like the shiny use the regular. Shinies are extras and shouldn't dominate someone's reasoning.
Man, this is really close. Before any results come in, I just want to say i couldn't have made it this far without the support of Wyverii who offered me advice and a critique at the very beginning and Wichu who showed me how there was always room for improvement. Thanks, guys.
