0 More Cover Design

I've never done a second post in one day before, but after playing around with some more cover designs, I'd like to get some feedback from people. Looking at the previous post and now this one, are any of these covers heading in the right direction, or do I need to try something else entirely? With these two below the only difference is the font used for my name at the bottom. If I did go with ones similar to this, are there different fonts and colors you think might work better? I kind of like red, but when reduced to a thumbnail it doesn't stand out as well as white or yellow.

This next one I just played with 'kerning', which changed the spread of the characters.
