Looks fantastic, great work there, Ikea do some great frames for projects like this, and reasonably priced too!
There's nothing better than pulling all the items you have for a movie and putting them behind glass, it makes them really pop - Plus i bet you can actually see them now, as apposed to having them on a shelf!
Can't help but wonder, if the backong board would benefit from being a darker colour, you can buy big A1 mount board sheets from ebay or hobbycraft shops - Relatively cheap as well. I think being a darker background would really make the items stand out.
