Special is right, you will be able to do all kinds of special things, like high lights on lettering, reflections that make your work special, water, and cloud effects.  The things you have always wanted to do, now you can. 

You can get into the Movies or Broadway Shows even the poster business fits right in with the Advertising Companies that do all the Art work for this industry. You could also do things like finger nails, wall or backdrop murals, things people want and need, but can’t find anyone to do it. You will be a hot item overnight.
