Decent job thru most of it, and no, I don't need some perfect 'Class-A' quality to get a storyline across. I do, however, wish to point out a little 'slouching on the job' near the end. You've come so far up to getting outright physical, why suddenly diminish the job at the fighting part? It cheapens the whole experience visually, especially when you switch from color animation to black and white sketch-work... Sorry, but that's just how I see it.
Even the Anime styles developed the 'chibi' scenes to theatrically display how childish people act when they get too excited or lose their temper(s). With deeply rooted traditions from Japan, most Anime traditions are based on a serious disapproval of that kind of outburst... but I digress.
Advice? Don't forget even a primitive storyboard will help you develop a project in manageable pieces. Then take regular breaks! You can 'burn out' easily if you concentrate too much on a single project at a time. Sometimes it's just better for you and the resulting product (even if it's a hobby) to just back off and remember to breathe and check out roses or a sunset for a while... do something (ANYTHING) else. The project will still be quietly waiting when you return.
As for the 'haters' out there who try to warn you for being lazy? Remember that you can't rush genius. Quick work ain't good, and good work ain't quick.
Because the only difference between genius and stupidity is that genius has its limits!
