lower the gradient map just a little of the purple and orange it's taking away from the depth a little bit and do a b/w gradient map set to luminosity that should help a ton
not bad i think u could maybe shapren the main bit in ur sig which would make it look much better,also the effects behind the head if they were actually closer to it i think it may look better. I think mabe add few ajd layers or so coz the balck cloudy bit looks a bit odd or jus add sum effects overall its nnot bad.GOOD work.
Actually the focal is sharpened. I tried more, but it got ugly after that And I sort of did do a b/w on lum, but yeah, the colors are fuei.
