Gaming Smoke token

When I saw BrayChristopher's excellent fire token for Flash Point: Fire Rescue (https://www.thingiverse.com/thing:2406292), I decided to create a smoke token to join it. So here it is!
In the images, you can see the smoke token together with a Flash Point Fireman for size comparison, and also the smoke token together with the fire token and the Fireman.

I'm new to 3d design and 3d printing, so please forgive any mistakes I may have made.
