I have used again after few years the Art Pen,I remember now why I stopped using them: meanwhile it works,it doesn't,than it gets stuck,you shake it and some inks drops out ,push it and a big drop goes on the comic page you nearly finished ruining the "b...dy" page,you open the pen first in the morning and it's all leaking and sticky,after an hour of working with it your hand it's marked with ink..etc.etc.
I'm still here folks!! No much time for sketching at the moment,but I've got here my first attempt at using Airbrush on Photoshop with two characters ,Johnny the Little Devil and Angelo the Little Angel ,a long standing project of mine..I got fed up after a while,I didn't know how to save selections etc. etc. all by hand ,a pain in the neck!! But ,I got it now,next job should be easier...pheww...
