If he has created the art in photoshop himself, then no copyright is infringed even if they do look very similar.

As for the name, this will only matter if the original name was trademarked. If not, he can call it whatever he wants.

if it's not copyright infringement, it's trade dress infringement. http://en.wikipedia.org/wiki/Trade_dress

either way, he's in the wrong. and the name is trademarked.

It's called "substantial similarity." One of the tests is whether a "reasonable observer" would be likely to mistake one for the other.

It's nice work but the author should've used different assets and a different name.

If you're in the UK that doesn't appear to be the case. I'm not particularly versed in copyright law, but take a look at this example where the work was just "similar"
