I see immediately that there's a weirdness about the muzzle on the right hand side of the page. The downward slope on that side should be less steep, and the curve toward the bottom should be much more acute. I am pretty happy with how the eyes came out - the reflectiveness and use of black in there feel pretty solid to me. I think I could profitably redraw the speaker tube on the right side to adjust the angle at which it projects, to make it parallel to the other one.
Here's the revised version:

As always, lots of room for improvement. I guess that's the human condition, and I would probably get super bored if there weren't always more things to learn.
Thanks for reading!
