Stellar work, I see a huge improvement. It fits the style of the mod so far too.
2 things:
-the trail seems a little long but I'm not sure if that can be changed easily.
-it looks like it wants to move a lot faster (not sure if anyone's found the code for this)
even if you don't change the speed perhaps other things could be done to give the illusion that it doesn't want to get there so quickly like reducing the change between each image in the booster animation.
