Your thoughts on the cover, please

I have three versions of the Perihelix cover; there are subtle colour and font differences.  My editor and sword designer likes one, I prefer another.  The text on the right is from the Kindle cover creator, and I can’t manage to find a match; the left and centre ones were the nearest I got. Maybe the centre one would be better semi-bold or normal from the current bold.

This is your chance to express a preference – just comment below!
