I like the way it is so far.I agree on the convoy light on the back,it needs to be painted.I forget if the tube style was white or blue.
Also,you could add u shaped (but with squared corners) latches to the tool clamp ares.The best way to make them,is to squeeze some small dia wire flat to make strap stock,then bend the legs and add.Now you may have to touch up the paint,but those would add just a little bit more...
