Well, it's just a pic., and if you're going that route it's better to do a decent quality pic.
The oshawott is pixely around the edges, and it doesn't look good. You could have solved that by selecting it, subtracting the selection by a few pixels, then feathering by 5px, inverting selection, then pushing the delete key. [ assuming he had his own layer, and you were using something decent like photoshop. ]
The text is read-able, but it's not as well as it could be, especially the smaller text. You should have put an outer-glow effect, and made that a shadow. Maybe even bold-faced the text.Other than the things missing, it's an alright little banner. I might VM you the way I would have done it, and include the PSD.
