I'm afraid that's the last of Naixoterk's works (unless, of course, he will return

Nice work. Keep it up.

It's not bad (though already 3rd S-49 we have ), but I have few remarks.
I agree with BK75 that window shade is not the best choice, but it's rather marginal thing.
More significantly though, I see a problem with canopy as a whole. I don't quite understad why You haven't simply recycled central (movable) part from S-49A on S-49C (and why that central part looks like it was made of 3 completely separate elements? - see (1) on the drawing below). Also, the rear part of canopy on 49A has that black-outlined-frame and on 49C not - I'd suggest to decide either way for both. Also, from the photos it seems to me that windscreen on both models differed (on 49A resembling Yak-3, on 49C resembling Yak-9) - here I shamelessly will suggest You to perhaps take a look on (my) drawings of these (see (2) below), where also instead of 3-pixel thick outline of the frame, I used simply darker shade of "fuselage" color.
It is also my sincere belief, that contour of the bottom part of the rear fuselage was (at least for the most part) a straight line (or at least a very gentle arc - same applies to these "ribs" on 49A and panel lines on 49C. (see (3) below).
The cooler/charger/? on 49C - considering it's shape, it could be arguably outlined in black (though I'd be against it personally) but definitely in much darker shade (to show that it's more than just another panel line) - and certainly the forward part of it must be outlined in black because it's standing out from the surface behind it ( https://www.flickr.com/photos/56388143@N06/19020641959 ) - I also have a feeling it was more vertically symmetrical (see (4) below).
Last but not least, there are some perfectly avoidable double-black lines (see (5) below).
