I admire anyone that puts the time in as you have, and am glad to see you going beyond your comfort zone.
I like it, but I am not a brushed metal fan, but that me. technivally it is a good cover that has been well put together.
if I may just suggect one thing. I would move the disney and pixar logo's up and down slightly so that the out border flows around the cover.
I would also love to see one with some colour as well. I would keep everything as it is but bring some colour through, so some elements where I suppose bleached.
I am more than capable of posting my designs to other sites, I don't need any help from others
