some awesome edits in here!
Just a couple of little tips i can share...
Don't forget everyone, Rain never falls in one uniform angle like a curtain. At speed, you can only really see a few patches of rain, again not a thick sheet falling down.
Rain fall closer to the camera will of course be larger than rain falling in the distance, so try and create a few different planes of rain each with different size, angle, length and visibility etc.
When adding water droplets to a car remember to use a real world, acurate scale. A car at a distance won't have large fist sized water drops on it's body work, infact from a distance it'll look more like slightly spread out camera noise.
I know these are from GT5 but take a look at my edits and notice my use of body work water droplets and rain angle etc etc
Oh, also, water droplets on a car travelling at speed will be pushed and blown by the wind as you can see on my Alfa edit.
But really, that's just me, like i always say...i know nothing. My way isn't always the right way...follow your heart and other various slogans.
Oh, and here is my reflection tutorial that could come in very handy for anyone who is finding it a bit tricky.

I'm looking forward to seeing more great work in here. 👍
