Hey jigu...welcome to the forums here
Here are some things I'd suggest for your animation
-Although the water looks quite nice right now....I think it's rippling a bit too fast
-It would be nice if you could have the water directly under the plane get all splashy and ripply....the wind force of the plane would definitely mix up the water underneath of it more than it is now
-Your afterburn particle size is waaaay too uniform, and the noise size is too low....you'll want the smoke to be a bit more wispy too
-Try adjusting the particle-age opacity of your particles so that they fade into existence for the first few frames of their age. Right now the fire just kinda pops into place at each frame (know what I mean?)
Overall it's a cool looking scene though....it'll be nice to see how this turns out
