i like it, but i dont like how the jet engine fire is... i mean its a good idea to put those in color but i dont like how... block/cut off it is... and i duno what the text says. Its good, but i prefer colored sigs.
It says "Phosphorous", the text behind it is throwaway text. I was paying homage to my old "Final Frontier" sig, with the whole black and white theme with the engines. Its supposed to be space, and longswords arnt that colorful anyway :/
As for the jets they are not block/cut off. I bumped up the contrast so it sorta looks that way. I could try to make it look more smooth, though.
