RP - unfortunately the .PSD file is way to big to post (40+ MB RAR or 50+ MB ZIP).

It isn't all that uncommon for me to run into 'blocks' like this - it happens all the time and usually the best thing I can do is just walk away from it - so to speak, work on something else for awhile and come back to it later.

I have some other ideas I can work on in the mean time.
