Whoa, man, please try to be a little more considerate and less harsh. We all have much to learn.
I do remember seeing a bit of your work before, Funmi, and I do think to a degree you have truly improved, and that's great, but there are still some areas which still need something.
Since effects don't really seem to be your strong-point, perhaps in future films it might be a a wise decision to simply avoid such effects. If your film does call for it, you might try something in camera, or perhaps try to write your way around any such need for computer effects. This would also save you some time since you wouldn't have to go through the process of adding such effects, and such time might be misused anyway since people seem to not be particularly fond of them.
As for set design, I really think you should put more effort in that, it can be very rewarding. Using green plates for an interior scene is probably an ill-advised choice, as green floor is usually used for outdoors rather than inside. It makes people think of grass, but there usually shouldn't be any grass on the floor inside. Try instead covering the floor with several grey plates, or some other colour to make the floor more interesting. Perhaps for certain situations even put designs into it. Once you're done a brick separator can be used to easily remove those things. And for the walls, I'd recommend never have all the studs face outward, instead try building a wall, preferably with colours which aren't too harsh as to place more emphasis upon the characters. Try to put detail on them and texture. Also, Flickr is a great place to look for inspiration. I often go there and just find a good LEGO fanatic's favourites list and I get a load of amazing models. And once you have built something, try posting it on BiM first to ask people for ideas for rectifications to improve it (I do that a lot, it really helps sometimes).
Unfortunately, you don't have a particularly good camera, but that's beyond most people's control due to the common brickfilmer's limited funds. However, it seems to do significantly better in brighter lighting conditions. Thus I'd strongly suggest trying to have your brickfilms be much brighter. Try shinning more lights on the set and/or turn up the exposure. The focus also is often not right on the figures, so try to make sure before every shot that they're as nice and clear as possible.
As for animation, try adding some more power to the punches, and a little bit more delicate smooth fluidity to the ends of movements.
On another note, though, I do really like the voice for the alien leader, and again, I do think you are improving. I hope you can keep that momentum.
I hope I've been helpful, but sorry for not being particularly positive.
