Hmm well, it's supposed to be dark, there's no lighting there...
I think there is. The yellow tunnel down there indicates there is a focal of light somewhere.
Anyway, even if its real dark down there (no sexual pun intended) I think the black particles kinda not suit there. But thats just me.
I am sure that little cube like spot isn't supposed to be there at the top left where her thigh first starts to show?
really nice looks good
It looks like you added some random effects right on top of here and did no editing to it at all...
I see your trying new stuff, but this looks SUPER sloppy imo. @Nymil
