I've been using 3D for some time now and I finally felt confident enough to go further than just blocking.
It started with some concepts for fun and ended up with a mini and very simple level design where I thought was the perfect opportunity to push my 3D skills and go as far as I could in Blender. (without exploding my computer).
For the final pieces I used a mix of eevee and cycles. Basically eevee for lit and bright areas and cycles for occlusion and darker areas. Plus a little of photobashing for plants and dirty ground.
I learned a lot about optimization, shading settings, lighting, modeling, camera animation.... haha so fun. Still so much to learn.
