Thanks for keeping things "Old School"! Animating from hand drawn is getting rare, and this being your first, I want to encourage more out of you.
At the same time, constructively... Even a terrible sound track is better / more entertaining than no sound track at all. It doesn't even have to have "great" or "standard" foley... (that's sound-FX) for those who don't know. I honestly think just a splash of even "cheesy" music, and a few sounds to "sell" the shot would spruce this up for your project to a top notch... at least for what it is.
Everything else, you hit at least the mark. These comments are just something to help out a bit, from my angle and view.
