The planet was pretty much free-hand. After the fact I find out that it is helpful to use white guache! WHAT! This would have made my life much much easier. With planet Earth I could have airbrushed everything and then went back in with white guache and got a better swirling cloud effect!
This just didn't work out for me! I have a hard time visualizing how to create the mask in what order. Then I made the mistake of FREE HANDING! Novice airbrushers SHOULDN'T free hand! I REPEAT....DO NOT FREE HAND. I tried to go back in and freehand the seeds and also the fuzz of the kiwi skin. I couldn't get close to the image to airbrush small. It just kept spider webbing on me. AHH. Frustration.
