Not bad, I watched the side by side comparison, and you did a pretty good job. If I were to pick on something, I'd go with the lighting and animation. Unlike the actual trailer, the lighting was somewhat bland throughout, and took away from the feel of the shots. The animation itself wasn't bad, but it was just simple animation (walk cycles, simple turns and arm movements). There wasn't a lot of complicated shots like the original. Still, I'm going to say very well done, as you still succeeded to transform the trailer into LEGO and keep it enjoyable and understandable. Better than anything I could've done.
