sorry to say demonchick but this is the worst piece of work i've seen you submit yet. the background is way too plain and it only has one vector brush there and the text doesn't suit the other colours that much at all. i suggest that you use the gradient tool for the background and add a few more brushes and/or effects to make it better. as for the text, you should choose a different colour, probably white of an off-colour white. please don't take this the wrong way, you are a good siggy maker and you have shown a lot of improvement, keep up the good work.
Really good! I would have gave a little larger font other then that great, you should have not used the background colour on the image of the character, you should have gave him a red or yellow color.
