Looking good! Seems like quite a sophisticated build - hopefully it's fairly robust. This one takes me back to the old Airfix 88mm set, which was one of the best kits they did in that range.
One query - are the wheels perhaps oversimplified? Here is what the wheels on this version looked like:
The spokes don't seem to curve outwards, and are further inside the rim. The bolt detail is also different. I realise you need to simplify them a bit, but the wheels are quite a prominent feature on the model, so it's worth getting them right.
