Nice work on this so far. Continued improvement as you've gone on.

Other people have mentioned the few areas to tweak with glossiness and so on so I won't, except to say with art sometimes less is more. There is a tendency to exaggerate cool effects like bump and shiny surfaces, but you have to fight that impulse and look at the overall composition as those aberrations sometimes stick out like a sore thumb.

Look forward to seeing more.
