Wellcome aboard Brewer!
Nice model - and excellent photography! Have you "photoshopped" images?
I like matte/flat look of your model, that is definitively authentic. Contrast between camouflage colours is probably OK; Massimo may say more (maybe if he converts image to b/w)...
Most obvious mistake on your model is
light blue cockpit. It should be
gray.
Say what you will about the accuracy of the VVS colors, this was a commission build and I used Tamiya acrylics per the customer's request.
Since you mentioned colours:
AMT-4 should look like green vegetation in summer; green and yellow only, no blue tinge and no gray.
AMT-12 is for shadows; it should be flat dark gray, almost black
AMT-1 is for earth or sand (not Sahara, more like preries dust if you are American or Canadian); it's yellow-ochre and gray, no red.
AMT-7 could be darker than yours and it should be pure blue, no gray, yellow or green
HTH,
