Pretty good so far. As for the cam. S.C.C.2 was the authorised base colour around this time which, looks a bit like milk chocolate depending on your POV/ monitor/ reading and research biases/ level of exposure and fading etc, etc, etc. The camouflage stripes could be S.C.C 1A dark brown or S.C.C. 14 black as an alternative. A number of paint brands do S.C.C.2 including Mig. Black later became the standard disruptive colour for the European theatre but is completely legit for 1942 and makes for better contrast.
Yours look pretty good to me.
