Not really
Well, to save Eswube some work, I'll lay down some obvious things I noticed:
1) Lots of grey spots where black outlining should be.
2) Shading needs work (there is none under the wings either).
3) Wheels should be more rounded.
4) Engines, cockpit, and wing/tail surfaces are very "plain", maybe add in some detailing/shading.
5) The type of shading you used is too close to one another where it is somewhat hard to see the difference.
6) Propellers shouldn't be simple straight lines, if you can't find a source with them, just leave them out.
7) Black lines are for 90 degree angles only
8) Smoother lines on the basic outline of the aircraft.
Did what I could just based off what you drew, other than that I have literally no idea what else to do because I can't tell what I'm looking at and I'm not familiar with this airplane.
