Top, nice depth, but ive seen that sig b4. Did u just do the same style or buy it off him? Cuz it even has the same things that look like they are falling down onto her. Bottom, can barely see the renders, try not to change render colors in sigs (at least not very much). Text really stands out, not enough color. Read some tuts. 4/10
That render is everywhere, but anyway, it was a custom-made. And as for the second, it's a banner advertisement. Both sigs have nice effects, the BG of the first looks good as well. 8/10 for both.
