better
much better than last time, but still needs some work. i see you cut out all of the tank, and also the dog is now cutout. the thing that still needs work is that the blood still appears randomly. right when the tank completely covers the dog is when you should put the blood thing in. that way nobody can see the blood appear randomly.
much better, tho. remember, your first few flashes are gonna present you with lots of hardship and troubles as far as quality and voting, so just keep at it. eventually it will be awesome.
here is one more thing you can do, try to draw up a background for the tank to drive on like a street or just a road or something. maybe with buildings or something. just an idea.
