There were some limitations on what he could do as far as color gradients and font sizes, but he came back to me with several options that I was really pleased with! It's a bit of a simplification of the original banner, but I have to say I'm really happy with how it turned out. The metallic gold is a nice touch (Of course I'm going to have to be incredibly careful when washing it and hang dry it to keep it looking nice)!
While I was at it I ordered up a couple other shirts (after all, shipping across the pond is expensive, so it made sense to order more than just one shirt), including another Thousand Sons shirt (which reminds me, I need to take some pics of the other two KSons shirts I've purchased) and a shirt with an Adeptus Arbites symbol that I quite liked. If you're interested in checking out his shirts, I would heartily recommend them - the owner was a pleasure to work with, and the quality of the printing and the shirts themselves are both top notch! At the owner of the shop's request, I'm not doing a direct link but drop me an email if you're interested and I'll point you in the right direction. :)
