My first banner attempts

I've been trying my hand at banner work in my spare time.  My idea was to make a few 1000x460 banners for my fic, Clocks of the Long Now , with each banner having a different character focus and corresponding treatment.  Large versions of my first two attempts are under the cut.

I'm new to this, so both positive and negative criticism are very much welcome.  Thanks!
