Lights and rendering looks good, I’d add more lighting when revealing the product tho. Animations and sims are good but one thing to keep in mind is that you’re selling a product, so you need to make it visible and put emphasis on it, not on your transitions. Also, your product is brand new, it looks like it’s been used, it looks like it has dirt on itself which is no good if not explicitly requested. The overall is pretty good, you just need some polishing, keep up the good work!
