A very good build indeed, and good camo too. But I have a question : did you add washes and pinwash to give your vehicle a well weathered look ? A pinwash would give it extra depth an make it even more beautiful.
For an overall wash you can brush on a very much thinned down burnt umber (oil paint), 95 % thinner, 5 % paint. A soft brush can do the trick. And a soft cloth can be used to remove the liquid in places. Not the whole tank, but area by area for good controll.
Pinwash : a bit thicker wash in fact, added by a fine, soft pointy brush, around nuts, bolts, in panel lines etc. It will find its way very easily.
