A Cover, for comments...
This is a work in progress: There's a blue line on the back cover, and I haven't installed the blurb on the back cover yet.
This is actually the second round for this book: Some of you will remember the cover design I started with, and you were right, it really doesn't work. I'm hoping I've hit closer to the mark this time.
Some specific questions:
1. The crosshairs in the title -- does this convey action/adventure? Crime drama?
2. Bigger crosshairs, or not over the title, or none at all?
3. Does the front need a background color?
4.Does the overall design work in principle?
Of course, as always, any thoughts or comments are welcome.
