need feedback for my new Mock Up site template please

[Eyescream]

A thought, I did a test and copied all elements (except bottom copyright with tiny eye images) and saved/exported the entire file of elements as a .png and tweaked a little in Photoshop then started a new website doc and imported the entire back elements as One file image.

Question, do you think this is better? To have one main file png image as background template for the site? or having the multiple png images seperated as in the first .web attached.

I am attaching the other .web I just did with the one background layer. Let me know thoughts on this if it makes a difference or not to have one main image for background or mulitples that I will be able to move around and adjust at whim. thanks.
