The art is consistent in what I have noticed is DC's in-house style, and the colours are more of the same, nothing special.

The art is not classically what you'd call good, but I love it to death. The pencils are rough and thick, and the inks unsubtle, which combine to give it a somewhat likable look that appears deceptively simple. Nitpicking: In one panel, OMAC appears to have merely four fingers on on hand. Seriously. That is the extent of my art criticism.
