3D-Daz Lighting & Rendering Feedback

[Greyscale Studio]

Hey everyone, so my post Looking for a seasoned daz3d user didn't give me any success to find a experienced Daz3D user, so I've kind of taken it upon myself to start learning Daz3D to do it myself, but now I need some feedback on my lighting / rendering quality as this is my first render ever created, I used a lot of pre-made assets but some lighting settings and rendering settings is handmade to suit my needs, if anyone has tips, tricks or ideas feel free to leave them in the comments below. I'd also appreciate harsh and realistic criticism.

Here's the render in question, (slightly NSFW but no nudity):
