I'd say, yes - push harder, ideed. Spledid work, even though incomplete, the work in this definitely shows, and even though it must have taken a lot of time and effort, I'd say working like this will definitely see you good reviews.
Pretty well done - though I understand it's a series of sketches and nothing supposed to be professionally finished, which is completely fine by all means, my only gripe is that certain action scenes have much louder audio than the background music, making it somewhat surprising/startling, almost. If you were to up the Background music or lower the effect volume, I probably would have given this a 4.5, but I'll give it a 4. Simplistic stick figures can sometimes be refreshing in worlds of detail and complication.
