Looks very nice, but lacks some focus due to alle the effects in front... U could crop V3 en put the person a bit more in the center, i think that might add focal
Last one is best, but i see this render a bit to much, im getting bored of it. But is a nice tag though.
I like it. Second one is my favorite, mostly because I don't really think B/W is that appealing. That's just me though. Still, good work on them.
