Just a Beautiful line drawing that I saw and put my spin on it...
That's a mighty finer job on your backshot, Mrd1i. Very awesome work, indeed from what I've looked, so far.
My big suggestion is that though your forms and perspective is getting there inclusively, then I'm not getting enough of the highly exaggerated action and foreshortening. Would you please loosen up your lines and graphic shapes with 30 minutes of 30 second pose warm-up drawings? (60 drawings) And also look into this video, please.
The reason why is because of two different reasons: First of all to make your lines the least itchiest, and the most loosest and smoother. Second of all is to check out the Manny Gould scene frame-by-frame with the Mark Kausler interview on the Bugs Bunny Bob Clampett-directed cartoon, Falling Hare (1943)
Good luck with your current goal and pursuit.
