Hope you don't mind me being really picky but it's only little things that 99.99% of people won't notice, however I still keep noticing that zig zag pattern that is used for paint chip on the front being repeated.
Also the lighting on the sandbags is very wrong, tone it down a lot as they are just sacks that are rough fibre so wouldn't reflect much light at all, only pick up a few shadows.
Tracks are much better though.
