i saw this via a retweet from BS Angel. The artist is Jamie Gee as you can see by the signature. You can follow him on Twitter at @Pero_Magic.
He’s got some other cool renderings on his profile, so I suggest checking those out and giving her a follow.
If you have some cool Halo art of know of someone else that does, please shoot me an e-mail at [email protected]. I enjoy promoting other fans artwork and giving them another venue to display their work.
