I like it. You've kept the cool blue look, but but gave it a bit of an icy look. I suppose one could interpret it as bland. It's still nice, all the same.
I don't like the font in use, and all non-image text would need a generic font available on all computers (such as Arial, Verdana, ect). Generally the design is good, but needs some improvement, such as layout and padding.
Times/New Roman is also a safe bet, as is Georgia in most cases and (yuck, yuck, yuck) Comic Sans. Don't use that last one.
On to the mock: the colours are great, and I like the overall idea although your use of the one font is almost overpowering. There are some good ideas mixed in with terrible ones, try and keep to something plain like Arial for the 'new messages'/username bit.
It's quite fresh and clean. Only the font shoud be changed.
I dont really think save all of them as images would be a good idea - it will take Asa a lot of time to do it and postpone loading the page.
