Last year I posted a drawing of Krystal from Star Fox Assault. I decided to redraw it to see how much I improved! Here's the original drawing...
...And here's the new redrawn version!
Here's both of them side by side.
Redrawing your old art is lots of fun and can show how much you've improved! I'd highly recommend that you try it out yourself!
I wouldn't call it an 'improvement' rather than a 'change' to be honest. It just looks so different. I think I actually like the earlier version more, with the smaller muzzle and wider head. But the newer one definitely has better shading, and background of course. You did great.
