Good work so far, I have been thinking that if you used templates your work would look more structured and would produce a better look. however I know this is a personal preference for the individual artist.
I don't think the DVD spine logo warrants any fancy patterning, this time around, it might look better if it was plain, maybe picking up the mid rust colouring from the front picture.
But remember you are the artist and this is just an opinion.
I am more than capable of posting my designs to other sites, I don't need any help from others
