I’ve never done GFX so this looks pretty good to me, and well, it is good!
What I could suggest you do is maybe work on is how the red light hits the person. It has an outline that’s a bit brighter than other things being hit by the light. It’s giving the person as if it has a neon material on it.
Also, you may want to make it a bit darker, because it just seems too bright for what kind of scene it is.
I love it! I just feel like the torso to the legs looks a little off. Like this photo…
It feels like the legs are going to detach at some point. The back hair color (gray) looks a little awkward to me, too (Unless it was intended!) I haven’t done GFX before, but I really like how the keypad was formed. Great job!
