Pretty dark, can't see anything that well. Not sure abou the blending because it's too dark, it's alright though just here's a huge tip. NEVER use lens flare as a lighting source. It just won't work out for begginers.
Are you talking about the tag in his sig or the one in his post? There is only lens flare lighting in his sig. As for the one in his post. You should bring out the focal more and the text. Gray text on gray doesn't work out too well.
Yeah.. =/ You did a good job with depth. I also see that you tried to make like a blood on the wall effect? To me it looks like there is glass in front of the wall and the blood is on that. You should work on that as well.
