Smokey Numbers Brushes - [link]
A complete brush pack of all 26 letters of the English alphabet. Each letter has two versions (in case you don't like the way the smoke works in one) and also comes in lower case, totaling four brushes per letter. This pack is enormous and should fulfill all your smokey lettering needs. Each and every letter was simulated separately, so there will be no repeated or reused smoke patterns.
105 brushes included! Very high resolution.
