Yep anything with high sss is a pain in the system (literally if your computer doesn't like doing that kind of thing because it can get pretty intensive) XD
I feel like you needed a tiny smidgeon of texture on the cigarette skin and butts as they look a bit on the smooth side. After that maybe play with the lighting a little bit more to get it a bit more atmosphere, even though it's alright I feel like you're lighting more to show off the models than lighting the scene.
All the assets look pretty good, I really love the barrel texture the most :)
Thank you for the feedback!
Your right, the cigarette skin does look a bit too smooth.
The scene does look a bit too bright, I should have made it a bit darker, so that it has more of a evening mood.
Maybe I play a bit more around with it and even add some colored lights, I think that could look really cool.
Thank you for the kind comment 💜
Adding different light types (if your computer can handle it because that again can make your render pretty intensive) would definitely help. Not all the lights need to cast shadows, some can just be used to add colour :)
