This theme looks great, nice and simple. The only potential criticism I have is the labels for mfc, date and rating are a bit hard to read, but that may look better when actually running the theme.
No need to apologize, that's the nature of doing themes which rely on created artwork. It's why I pretty much never use themes like that and caution people about going down that road. You can do some really cool looking stuff with custom assets but unless you plan on implementing it on a small scale it's a lot of work to make happen, which deters a lot of users.
