Those black things on his shoulders aren't actually part of him. ;)
Why blame it on poor J.J.? He didn't make R2, and why should he be expected to know exactly how R2 should look? I can't figure out what's wrong with him without a comparison picture, and I think it's perfectly reasonable that R2's been modified some time in the past 30 years. At least he looks used and not clean and shiny.
This is R2, Star Wars style. Note the height of the dome.
