Hey, Can anybody give me a quick critique?

There are a few things I know I need to work on like the start of the growth and the lightening but I think I have a handle on what to do with those.

The big problem I'm having is trying to slow down the particles enough to make the distance believable without losing the density. I need this thing to look VERY far off but massively huge at the same time. To that end the speed across the horizon isn't working either but that is an easy fix.

I welcome all suggestions and ideas. Thanks in advance for the input.

Can you try lowering the Velocity and Increasing the Birth Rate? I'm guessing you're using Particular? I don't have Particular so I can't give you much input on that...

As for the lightning, I've never seen lightning inside a tornado. I would suggest putting the lightning on the left side of the screen. You could also duplicate the clouds and mask out a section a increase the brightness when the lightning strikes.

Check out Aharon Rabinowitz's tutorial on creating weather.

look ok for start

few things i would fix are

the color more lighter grey
debri/object at base that come from the ground
and a shadow on the footage ground of the tornado.

looks good so far! yeah I agree with dataflow: the color should be lighter grey.
try to make the tornado less opaque and use match grain on the tornado!
After that add noise to the plate and the tornado and add a little camera shake like wiggle(5,15) or something like that! Should look alot better this way!

yeah I agree with dataflow and speedbreaker. It is a nice effect but just needs that little bit more. add those things and it will look great. :)

Also, don't tornado's come from the clouds to the ground, not the reverse?

yeah they form in the clouds but you start seeing the base first (from the debri)

Actually they sort of form both on the ground and from the clouds and meet somewhere in between but I'll worry about that later! :)

Does anybody have any suggestions on how to push this storm about 10 miles away?! I will mask out the horizon spillover later. This is a killer F5!!

A few other things I have tried was using Depth of field on the comp camera but that didn't have any effect for some reason.

there reason it looks like it forms on the ground is because you cant see a tornado untell it collects debri from the ground.

first video in my last post show that happening

covering the the base of tornado with foreground on footage will help make it look far away
