Inkworm, I know the difference between a D-9 and D-13 as I'm generally interested in german Luftwaffe planes. I mean that the engine itself is too fat, also I think shape should be in a straight line from the engine to the front windscreen.
I have just compared your profile with this:

BTW: the wing should be RLM 75 and natuarl metal, but at the restored plane they painted it RLM76 instead of natural metal.
Cheers,
