I don't have the program, never used it before because it's too expensive. Anyway, I wannna create a banner for a facebook / Internet group that I am in. We are Dungeons and Heathens. 

A D&D group from some youtubers. I was thinking of somehow combining these two pictures. For the first picture, the book, I am manely interested in the artwork for the cover, not the actual book itself. The demon guy with the two guys on top mostly. 

 

 

 

 

and this one

 

 

 

 

 

But I am not sure exactly how it should look. OF course, other really good ideas are fine as well. Make it something like 2400x 550? or 600? You know, the kind of banner size you see at the header of a forum, facebook profile, youtube profile etc. That kind of size. I am thinking maybe somehow combine these pictures, but if other people have other better ideas that would be great too! Maybe find a way to use the other D&D or heathen/atheist related symbols or whatever. Like maybe using this, but replace the second D with an H?

As a concept I put this together. Is this sorta what you are meaning?
