Very nice looking model. From a professional standpoint, there are some criticisms: 1. naming and model hierarchy organization could be much better. Nearly all elements are left with default names and the hierarchy is more or less flat. Proper, hierarchical grouping would make mechanical rigging a breeze. 2. Meshes are of inconsistent poly density and are generally unnecessarily dense. (This doesn't matter quite as much for film/television but it's a frame killer for realtime.) 3. UV layouts are mostly per-mesh. 4. Scale is arbitrary. Track width was, I think, 2 meters. Dolly track is 62cm wide, center to center of the rails. Rails should be 32-38mm or thereabouts (rail size varies by manufacturer but track width is standard.) Proportions are fine though, so it scales without issue. To reiterate - I'm pleased with the model, at the price I was able to buy it and fix the above for my use and not feel cheated. Unique items like this - that really break from the pack of generic "here's another lamp!" models are essential. A complete collection of set equipment would be a godsend. Film sound cart, grip gear cart, cranes, lights, etc. would be instant purchases.
