I have been working on this environment for a month now. I got the idea from here. I am familiar with UE4 but this is my first attempt at an environment. I wanted to practice Houdini , Blender & UE4 & this scene looked like a good start. I will post breakdowns in the upcoming weeks. Please gim me feedbacks (´・ω・`).
I think you would win a lot by trying harder to make your work appealing in the wording as much as the render, removing that sad emote from your title and try to make it sounds cooler than "the generic crystal cave" would be a good first step. I also see the same pattern with your lighting, imo your screenshot is taken…
