Articuno_Rocks: I adore the text, but am not a fan of the three images. But since it fits the theme so well, I'd give you a 9/10.
cooloolcool: Sprites on a plain green background with default dark red text... good lord. Try creating the banner
around the sprites; try to blend them well with a background having some relation to the focal point. And try experimenting with the text, I'm sure you'll find a better color than that dreadful red. 3/10
SmartD: The images are lovely, I love the backgrounds in each of them. However, I feel the text lets your sig down; there is just too much kerning. 8/10.
iPokemon: Great banner, well done overall. Text fits nicely, however I'd recommend adding a line space after the banner, but that's just me. 8/10.
Flame Mistress: I am really liking the text below the banner, that's formatted well. The banner's good as well, but the text on it ... please don't use that much drop shadow. Try a contrasting color. 7/10.
Here's a nice little resource for all y'all:
