I thought this was a decent entry into the series. What makes it work is that you have dramatically changed the background. It may not look like much, but it shows you want something different. I just love the silly expression you have on your face. Tongue sticking out to the side is always goofy. It is kind of scary as you're a floating head in the sky.
That reminds me of Phineas and Ferb Mission Marvel special I saw last night. The clouds are done nicely too. I remember never being able to draw realistic clouds in art class. That seems like it's where a lot of older stuff should come from. The hair was also really good.
