Sue- I am going to watch this with great interest- as to failure- I've already "plowed that field" for you with the hippo!
I FEEL your pain. I don't do airbrush so I may never finish the hippo, nor ever do another piece like that!
I would have loved to try some still life with large smooth surfaces, but no way if the only way to do it is with an airbrush. I was hoping someone could help me with the hippo but no one had any suggestions so- I'm hoping YOU can figure it out!
I'll be back to check it out. It looks great so far. GOOD LUCK with that skin.
