Text: Takes all my attention.. Which should normally be on the render. Just some advice: Try to always lower the opacity of the text, but just a little. Also some clipping masks would help it look better, but not always. If you use a gradient as the text's color, use some blending modes[in your text for example all i can say is "damn.. :\".. Usually gradient maps are not that great for text, just when you get better in gfx'in. I know very few ppl that can actually make them look cool with gradient maps.. Try to use simple colors, but never strong ones like 'purple,orange,green,red,blue [you know..] only if the sig/banner whatever it's meant to be colorful, or if you use them for a subtext. Try to use dark colors or lighter colors [depending on the sig.. ]. Also never make the text that big and try to make it blend.. Never put it over the focal, make it smaller or at that size it would look fine if you lowered the opacity and maybe change the blending mode. Also try to always put it near the focal up or down... [not meaning really up or really down.. I mean not in the middle.. Like it's here]
I have more to say but I'm too lazy so I'll leave it like this.
About the rest of the sig.. mehh it looks okay.
