Is that some sort of toy dog on the unit's insignia??? The puma with the Bf 109 had more "panache" as we French say...
I agree with Serval about the pure black and pure white. Are they ever existent in nature? Even if they are, I think pure white should be used only to represent void on a drawing.
I'd also make the panel lines more discreet. I like the way you've captured the shape of the aircraft. It looks more massive than it usually does on profiles but I like that. Brings out the "big brute" side of the Fw 190.
