Very nice work! 
(I did'nt know what Antiaris was: I recognized a corruption floating monster in the "R"... and after a google search I found out that it is a Terraria Mod) 
I actually think the black bg works well to blend this back. But I agree a frame might be cool!
wow.. That is something else! Maybe a transparant BG would be better, or some nice decorated frame.
Cool. It's like a cross between some demoscene stuff and the logo to Abadox or something.
