Hm. Well, I've been drawing a comic with cartoon birds for the last two weeks for an AP Studio Art assignment. For most of the characters I just have them use their wings as fingerless arms (picking stuff up "powerpuff girl style"). I gave one of the characters more human arms and just stuck his wings on his back. Here's a panel that has both types:


Also, I have a little bit of criticism on the Red Dragon logo. First, as I already pointed out, you have to be careful with your aliasing (note the white dots along the sides of the outlines). If you're going to use the fillbucket tool to color, make sure you have sharp, aliased (blocky, not smooth) lines.
The wing over the orb is kind of hard to make out as a wing, as it's too straight and flap-like. Practice drawing wings a bit; dragons usually have bat-style wings, which is essentially a hand with long, webbed fingers. The following image shows wings/arms pretty well:


Also, I'd make the body of the dragon darker. The light from the orb makes the wings stand out too much, and the bright pink is kind of hard to differentiate from the orb when not zoomed in.
