Nabatea – Innerscape book 3 cover

Still heaps of work to do, but I’m kind of pleased how this last cover turned out. Again, it’s still a mockup but I’d appreciate some feedback. Too bold? Too hard to see? Too something else??

I really need fresh eyes so please tell me if you notice something wrong. I also need to know whether the three covers provide enough visual continuity to make it obvious this is a series?

In particular, should I change no.1 to be more like 2 and 3 in terms of the circuit board wires and size of title?

Thanks
