not a bad attempt man. diggin on the ideas that you've got going on here, but i'd like to offer you a word of encouragement on it.
be sure to consider your "compostion". you have a good eye, but the focus of each piece seems to lack focus. there doesn't seem to be any reason behind what's in the banners is in there if you know what i mean.
composition is key to designing anything, be it visual or otherwise. close consideration for the structure of the whole piece and attention to detail are the biggest issuse.
but keep up with it man, you'll get it.
