Yep, slowly moving skeletons muttering nonsense is exactly what I think of when Halloween comes around.

Just kidding, but next time, you may want to do more than eight seconds of animation. Especially if the total running length is all of 27 seconds. Having the titles/credits run longer than the movie itself is sorta unprofessional, so if you want to improve the overall quality of your films, that would be one thing that would need fixing.

LDD is really limiting on most features, and thanks to those limits, the animation came out choppy, the lighting flat, and the texturing dull. Because of that, if you wish to continue with CGI Lego animations, I'd highly recommend that you try out Blender. If you don't know, it's a 3D program with all the goodies already built-in to make fantastic 3D animations.

Now, one thing you could easily improve next time is the set. This had a wall two bricks high with a tile on top, on a baseplate...And that was it. The cool part about CGI animation is the ability to add more bricks, and not having to worry about table space or cost. With LDD's large library of parts, you can make some great sets for your movies, so next time, why don't you give that a try.

Other than the above, there isn't much to comment on. There were no sounds or music. And the chanting/singing/whatever it was couldn't be understood.

I see that this is your first post, and that you're new to the site.
So before you get too involved, it would be a good idea for you to check out the "Beginner's Guide to Bricks In Motion."
