ZaPhOd, the green is to signify the Company he belongs to (4th Company in this case), so it has to be there, unfortunately.
Only thing I don't like is that the boltpistol's barrel is not drilled out. Otherwise, an excellent miniature!
The blue is a bit flat compared to the red with regard to highlights and shading. I think the green trim is too much and you could really darkline around the "U" and also the grooves of the shoulder pads. I do liek the helmet though and the gun, though the barrel is a shame :D
