Inside pages are cool, nothing i would change.
The cover is a bit different from your inside pages. Need to give it the same flow throughout the magazine.
Scan lines make it horrible and hard to read, this is not web 2.0
If doing a logo, i would keep it one single colour that can be changed. Take a look at Evo Covers, they usually take a spot colour from the cover shot to stay in the theme. Text in the circle should be over to the right ie center. Personally i would drop the circle. Use that white space you have their with the sky, use the same technique you use with the colour background text up there. I would take some of that lovely red you see in the right hand side of the photograph. Also with Zero on the title background.
I like you.
