Holy Crap - That's just inspirational !
what airbrush are you using ?
will you seal your work with triple Thick ?
Pic below of the air brush and compressor i bought.. an 'Artlogic' brand AC335. I looked at three different airbrushes when i bought this, this one was the middle of the range one they had, works well.
And yes the BG will be sealed with Triple Thick.
So far ive only used the airbrush on small areas.. anything large i sprayed with the pressure pack spray paints.. ie i did the DRACULA lettering with the spray paint.
