Just so u know, the Steve model is called the Default model, and the Alex one is called the Slim. U can choose which one u want when u pick ur skin on ur Account page on Minecraft.net. If ur going for slim and u use a default model, u can get a couple of errors (like I found out when getting my skin) but if ur using the Default model u should be fine. Not meaning to be rude or anything but i just thought i'd tell u. :)
