lol, /agree a bit on the flow thing. Although I can tell the direction it's heading in, the flow is still a bit....clouded. But /disagree on the render popping out part. Render fits in perfectly with the rest of the sig. And if you're talking about the lighting effect, well it's obvious why that's there. The render is the focal point, it shouldn't be sitting in the back with the rest of the background. It should be standing out more.
Ha thought it was my screen i cleaned it for nothing xD and hey your a great artist i see so much potential in you just learn a few more techniques . If you can go another day who knows whats gonna happen :)
