Howdy,
first of all, what an amazing course! It was really instructive and full of tips! I had some previous experience with Blender, specifically with a famous Youtube Donut Tutorial but here I’ve learned a bit more about modelling.
Here’s my own scene:
I’ve decided to do in in portrait mode since I wanted to have a nice night scenery with a (low-poly) moon. I also added a few more things like a rooster at the beam, fireflies and fog on the pond and volumetric smoke. I also played with world texture and lighting. The stars are rendered procedurally and combined with Blender’s sky texture. I used some additional Youtube tutorials to made these adjustments. I’m really satisfied with the result.
Thank you and I hope my render will inspire other aspiring “Blenderers”
