I think the standout aspect of this film for me was the lighting. You did a nice job of avoiding the bland flat lighting that afflicts many brickfilms. The concept was interesting; it might have benefited from a larger variety of games being played, but with the limitations of LEGO, I can understand why that would have been difficult. Voice acting was decent considering it was recorded during THAC by two people who were working on their own films, and the guy who played Death sounds mighty handsome. I hear he's still acting for any dedicated directors who ask nicely.
My largest criticism would be that the cinematography strayed at times, with the minifigures' heads being cut off at odd places and an occasional shot with too much empty space. A little bit more animation during dialogue scenes would probably make them feel more lively as well. I expect both will improve with practice more than anything. I'm eager to see your next film.
