I think his Nightwing run showed that when he wasn't tracing porn, Land was a decent artist. First time I saw his work I was impressed, and then I started to notice that his Black Canary looked just like his Sue Storm who looked just like his Emma Frost. They were all the same exact woman with different hair styles.
I will say, though, when has to do characters he can't find on the web or in magazines he does a half-way decent job (but that's not often).
