It's amazingly bad.
The webs are not webs, the pattern is screwwed up for no reason and there's some god-ugly silver things in his boots which I'm undecided wheteher I want to know the reasons for or not. Ah and then we have a horrific indentation on the back just to allow a long spider be there. Couldn't they have made a little smaller/shorter spider instead? But then again, was any of the changes necessary or is any of those making a great contribution the original design lacked of?
Sure, with a lot of shadows and a crouching Spiderman you miss a lot of the changes and the whole thing looks good, but I kinda know that Spiderman won't be in the shadows and crouching in every frame he's going to be in.
