Thanks all for the feedback. I was pretty happy with how he turned out.
The battledress jacket was base coated in Vallejo English Uniform which seemed a little too dark and brown so I decided to only do highlights. 1st highlight was English Uniform + Vallejo Khaki, 2nd highlight added some buff to that mix. I ended up with a glaze coat of thinned 1st highlights to try and tie it together. Dark details and deeper shadows were picked out with Vallejo Dark Brown wash.
The sheepskin was basecoat of Vallejo Buff, then followed up with Vallejo Ivory, sticking to the peaks & tips of the textures where possible. A few lowlight areas where shaded in with Ivory with a dot of black added. A light Brown Vallejo wash gave it some depth and hopefully a more realistic tone.
