For good Machinima standards, you did horrible. For a school project, yeah, you did pretty good. Teachers eat up anything like this no matter how bad you do. I remember whipping up a lego animation in one night on a summary of some book I didn't even barely read in the 4th grade. Everyone loved it.
Teachers love anything they haven't ever seen before. Whether it be machinima from a video game, a diorama made out of legos or whatever.
I agree this is no where near Machinima standards, but perfect practice and time can help me get better.
