I like the Panzerwerfer 42, and yours looks good from here Gary. Ufortunantely the colouring of the pics is not helping, have you tried to adjust the white balance of your camera? I'd like to see that camo in good light, it looks very nice.
There seems to be a gap between the top and bottom of the engine compartment, but other than that I don't see anything to add.
The plastic tracks are not very impressive, (the tracks that is, not your work with them..

) I build the Azimut version yonks ago, and although the plastic italeri tracks where included, I replaced them with MB indy-link tracks. I you can I would consider replacing them. Well worth it, as they really add the finishing touch to the model.
Show us some more....
Cheers
