I see what you mean. The idea is pretty nice imo, but the pictures are REALLY looking as if you just pasted onto it. At the edges they arent smooth, and the name also has white pixels around.
I suggest not using the standard RMXP characters, and also just typing a title in it other then using a 3D model for it.
For more information on how to make a nice image, you can look at some tutsites. Do you use photoshop? For PS I like psd.tutsplus.com, they have alot of nice tutorials to follow.
