Greg Land first got a job with an independent publisher as the artist for StormQuest after advertising himself at a Mid-Ohio Con comic convention.

[citation needed] After that, he was hired by DC Comics in 1999 to finish the covers for Birds of Prey, based on the sketches of Brian Stelfreeze.

This led to a collaboration with writer Greg Pak as the main artist of X-Men: Phoenix – Endsong.

Land has been accused of going beyond the accepted bounds of photographic reference, lifting images from sources that include hardcore pornography, and copying them into his pages outright with minimal Photoshop alterations to make the work appear to be an original drawing, a reputation he developed from his work on Ultimate Fantastic Four and Ultimate Power.
