A friend of mine asked me for a print of an old F-86 I drew a long time ago. I couldn't believe how bad it is. Thank God, I've learned stuff since then.

Anyway, I figured I would show the old and new version just for the fun of it:
There is still lots of room for improvement, but no time so I'll stick to that. I'm not too unhappy with the end result anyway. If I kept up, I would have redrawn the whole thing.
I thought maybe other profilers who have improved some of their older drawings could also post them in this thread. Of course, people who have drawn superlative Spitfires and Zeroes and then improved them (99% perfection to 99.3%) needn't apply.
I thought it could make for an amusing thread on how we can improve our technique.
