I like the outcome of your last signature, the one which apparently stars G-Dragon, I wouldn't know, I'm not really into K-pop
).
I must admit that's one good blending and the colors are really matching, getting rid of that side bar was a good decision xD. I would play a bit more with the lightning to get a better depth, but that only for slight improvements ^^. The text looks a tad odd since it's not blended at all, but the font is pretty good. All in all, great work, keep it up
Oh, and now I remembered, I really liked your Altair one :>
