What I would recommend is doing a bit of the blur tool around the edges of yourself a little bit, NOT TOO MUCH, but a smidge, before putting it into the graphic. It would help get rid of a bit of the jaggedness that you sort of see... Otherwise, great job, heh.
Also, is that a specific font you're using for the EE logo or is that premade?
EDIT: From past experiences with Photoshop, it is extremely easier to do some cutting and cropping yourself out when you're in front of a solid colored wall, which it seems like what you're doing.
