We're thinking about churches

I have this series of churches I've done, the four of them are pictured here.

But I don't think I'm done yet with churches.  I like that type of massive architecture, and the feel that the older ones have.

But I'm thinking that I want to take this in a different direction. 

I just don't know what that different direction wants to be.

Do I want different views of the same churches, different angles, wilder colors, more exaggeration, or should I just stay on the same path and find some other churches that need to have their pictures painted.

What do you think?
