It's a nice effort but...
First of all, why have You made two completely separate (in geometrical terms) drawings - for Ki-43-I and Ki-43-II/III?
It was the same plane all the time, just with different engine and elements of equipment.
Am I right to suspect, that You've used two completely unrelated sets of plans? (or just one set, but from 'Squadron-Signal Aircraft in Action' series?
If I may suggest something for the future: when drawing an aircraft that had multiple versions, choose one version (preferably the one that You have best sources) and only make relevant (for other versions) changes to it, remembering that drawings from various sources could be inaccurate, distorted during scaling, copying etc. etc.
Another thing is that the hatch in the rear fuselage (behind the cockpit) was actually present only on the left
side of the fuselage.
(Plus there are some details I don't like styllistically, but that's secondary thing.)
