Traction

Well, my new novel "And Ye Shall Be As Gods" so far has not gotten a lot of traction (although those who've read it and commented have been very positive).
I wonder if the title and cover are a little (a lot?) too intimidating. Because my first, "The Dogs...Barking sparked a lot of interest, and the cover and title were a lot warmer, I think.
I'd love to hear from anyone out there on this point as marketing is not my strong point.
