No offense to anyone, but I would like to do things on my own. If you want to help, go ahead and write reviews for people here. Just be sure that I will write a very helpful one also.
Haseo: First of all, the girl seems to take up most of the space, which is good for a focal. One of the first problems I see, is the rainbow effects behind her. They look nice, but aren't moving with the flow since they're only behind her. And it seems to big to keep someone looking at a specific part of her body. The "tattoo" seems to be put on her skin like a week ago. I suggest lowering the opacity just a bit to make it more realistic.
Sorry, .Core I want to try this one. Ok, so the colors are great. I'm guessing you took the eyedropper tool to take the colors from the render. That's what I do when I want to create a good color scheme, so kudos on that. A problem I have with it is the smudging on the yellow background. It just seems too large for me, so it's kind of awkward. Try resizing to a size such as 355x125px. It would create a better focal point of your render, instead of all of the little areas of drastic color. Also, your render just sits there. I suggest putting an outer glow or a drop shadow to make him seem more in place. A border would create boundries so you're not lead back onto the thread. And the text shouldn't be smudged, but read. That's just my input.
I guarantee you won't be disappointed. Ok, megathumbs, your sig seems a little...plain. The background is just a quick paint bucket, and some weird online images, I'm guessing, which aren't cut out well. Not to mention the text which is stock. Try looking on google for custom fonts. Are you using Paint?
It is now Public Extensive Critique. P.S. Someone should try to get this stickied. Not me though, I dont want to go campaigning around customer service for stickies on my own threads.
Thats awesome Nor, the bg seems to really go with the render and the glow works pretty well. The lines seem kinda random and theres some negative space on the right, but other than that its amzing. You've gotten really good.
