Here are some tutorials of airbrush hosted on youtube, I hope these will give you some inspiration and pointers. If you have any questions or suggestions, feel free to contact me or leave a message here.
I have never been a fan of airbrushed nail designs....until I saw your work a while back. Love how you bring in 'depth/ light' ... a true airbrushing talent. Would love to watch you working 'live'.
Excellent
