/3/ - 3DCG

Hi /3/, retarded /g/ent here who's fairly new to 3D, I used to do a ton of intros and stuff for kids Call of Duty montages back in HS in C4D and got pretty comfortable with it, eventually branched out into some dumb abstract 3D art and modelled a concept home for a mate, but was never very good. I haven't really touched it for the 5 years since but in the mean time have taught myself some OpenGL and DirectX and have a fairly decent understanding of the fundamental technical aspect of /3/.
Anyway I'm looking to make 3D porn (just posters) but super high quality, I want chromatic aberration, sub surface scattering and every other dumb gimicky re-shade effect, but it's all coming out horrible (pic-related)

My methodology so far has been to just use MMD tool for C4D and deviant art models but with my own lighting studios and textures, following lots of tutorials for both of them but after hours of greyscale gorilla and tweaking settings, it still looks like ass

What do /3/? What path should I follow?
