I really want to like this, as it appears to be really well painted, but it is too ...blue...
Well, Monotone would be a better word, but between the light blue of the treads, the blue wash on the metallics and even the 'bluish-green' glow of the windshield (if...it has one) makes things a bit muddy. If the red/brown had been a bit darker, and more intense, it may have helped.
just a thought...
