Welcome to the class @annarudzka! Thanks for sharing a bit about yourself. I find it very interesting that your jewelers profession led you to Blender. 7 or 8 years ago my best friend asked me to model a custom ring that he was going to get fabricated for his fiance. It was a lot of fun and rewarding using Blender for such a practical reason.
Your treasure chest is excellent! Nearly 100% authentic with the one from the course. The only suggestion from me is to “un-straighten” the straight edges as a whole. In the last video I opted to add a lattice modifier to eliminate the over-abundance of straight edges in the treasure chest. It should really hammer home the fun-loving lo-poly style.
Even still, you’ve earned an A in my book 👍
PS: Your English is entirely understandable 🙂
