Sorry, but I'm not as forgiving as the others. And it's not just the "weathering". You should really try to improve your basic painting skills too, and I strongly suggest to use at least some reference photos before you start. Good and useful tutorials can be found all around the net, exploiting them will surely help you getting better results.

Glad that not I'm the only one using (struggling with) Sketchup...

bought and printed the digital kit of the harvester.... looks amazing, even in half the size it is offered as a build-ready kit. awesome engineering, 100% accurate as far as I can judge
