Looking good, but it could be even better !
Ithink the model could be a little less 'flat', especially compared to your reference pic, maybe scale up 25% on the vertical axis and/or narrow it down a bit.
The team colors look somewhat wrong, though : too bright and a bit too saturated, look at Valve's truck model for reference if you must. RED's truck should be more brownish than flashing bright red, BLU's truck should be somewhat more teal in color and definitely darker. The neutral orange truck is looking alright.
