This is a good effort (especially after the endless hordes of crap today.) The movie looks fine, despite your worries about pointed drawings...the robot in particular is really well done, and the human characters at least look and move like people. I really like the introduction - feels very professional, and sets a nice mood.
The most glaring problem was probably the voice acting - the lead character sounds rather weird, usually monotone and inflecting in all sorts of weird places (which is why I actually gave this humor rating...it's kind of funny.) The grammar is also somewhat messed up....I know you mentioned that grammar and voice scripting aren't your strengths, but you could probably at least get someone to spell and grammar check your dialogue before making the movie. The story is also kind of vague..it's mysterious and all, which is interesting, but it just puts out a lot of questions without really answering or saying much. Perhaps try and include a little more plot in the next few episodes.
Still, good effort on this one.
