Dig the render on your first, as well as the text placement, 9/10 Second one, you can see this weird black line that doesn't go with the rest of the helmet, other than that, great job.
It is located in Toi's full sig tutorial, look for the thread in the tutorial section in these forums, Oh yeah, your render has been used alot, but the way you made the lighting gave it that boost, great job, very emotional, 8/10
What are you sorry for? lol 7.5/10 for both, too bland of colors, second one isn't blended and the background is boring.
