I'm OK with most of it. I'm fine with the fact that it uses Photoshop elements (and pleased that it mostly matches the style and tone of LOTR). I understand the need for the floating heads (though I certainly don't love them at all). I would have liked a bit more keyline art like LOTR has (for example the arrow key line art on LOTR that pass through several inserts pointing at the main shots).
In the spirit of constructive criticism, here are a few things that bother me, and some suggestions.
Each of the dwarf names have 'The Dwarf' tacked on to the end in small font with varying font tracking applied to stretch or compress it. That they are dwarves seems redundant, is this text really needed? I hope the license isn't forcing that there. Thankfully with Bilbo it doesn't say 'The Hobbit' or Gandalf 'The Wizard'. That the 'The Dwarf' text varies in tracking (spacing) is not pleasing from a visual perspective. It looks bad. The names would be much more striking/clean without the extra text.
I find the 'L' 'O' 'C' 'K' coin text to be an unneeded cluttering element. As already stated it screws up the art of the dragon's wings. The LCD screen would a much more natural place to explain the significance of these rollovers with a graphic that periodically shows the rollovers and explains they are for qualifying a lock. Sometimes it's OK to let an element explain itself, I don't think people will be confused enough NOT to play the game if these aren't labeled.
I don't understand the what looks like chunks of ice up in the barrel chase area. Maybe it could be changed for something a little more visually appealing and relevant?
Certainly it would be nice to have variability in the cut/paste elements like the trap door frames as has been mentioned already.
Not sure I'm in love with having the dragon pictured at small scale in the center of the field. As stated the dragon is already going to be prominently featured as an animatronic in the upper left. It seems a more powerful statement would have just to have gone with the lonely mountain in the middle, but maybe that would be too plain an area then.
