For the ship one, i would recommend flipping the ship horizontally because that angle doesnt seem to give off the right effect. Its going against the perspective of the "window"
agreed... the render on the irobot one kinda looks just stuck on there.... more blending maybe but the background is so beautifull ! don't cover it
The Mirrors Edge sig rocks man! How did you do that? Anyways awesome stuff you got here, you have a cool style for sig making. GL.
Love the concept of the window one, go with some of the idea's of above and that'd be a great sig. Like the Mirrors Edge one as well.
In the first two the renders really don't look like they fit at all. Both of the verts are nice, though.
I only have one word to describe the first vertical... SICK! I love it cause it's such an original and well produced signature. The others are nice. I like the concept of the first although I think you could have done better. The background of the second is awesome
