Hey there, thanks for posting this. Looks like you are off to a good start IMO. Going from memory, the shape and outlines look to be going together well.
The nose shading, I seem to recall that the somewhat boxy form of the fuselage (which you have captured), tends to become progressively softer farther down the cone? I'll have to double check, but if so, then I'd say the shading could be gently wider (and lighter) as it approaches the tip of the nose.
