Good choice on the 'Clash of Gods' for the series title.
The cover grabbed my eye to an extent, although I suspect that if I'd been scanning through a selection of books on Amazon or on a shelf I'd have placed it in the 'contemporary thriller' rather than the 'fantasy' genre - mainly because of the Capitol building. Nothing wrong with that. In fact, it might be a good thing if it differentiates it from more 'medieval' style fantasy, since ,from your description, it's a mix of both!
If I may be brutally honest, though, while there's nothing bad about it... truthfully I think it's a workmanlike cover rather than truly eye-catching.
