Wow! Great prezzies Harrison! That airbrush is the business mate! Make sure you practice lots before hitting a model. A good way is to use ordinary water colour paints, and spray onto thin card or drawing paper, to get used to the 'feel' and learn how to do various effects. The cheap bottles of liquid paint, in basic colours, available from kiddies toy stores are ideal for practicing, and always make sure the 'brush is thoroughly cleaned immediately after use.
You got a good haul of some nice kits too - wish I got birthday prezzies!!
