NO NO NO...... you will damage the nozzle
remove the seals (if any) and soak the nozzle in createx restorer if you have some, or isopropyl alcohol, use a long bristle artist hairy brush to work inside the nozzle, repeat. rinse clean with water, reassemble and check the spray, if not as it should be then repeat the soak.
which version of createx are you using ? "Createx airbrush colour" is designed for textiles / craft application not artwork. needs a .5 needle and around 50psi
What airbrush are you using, with what size needle ?
You should be using wicked/wicked detail / illustration for your artwork ( or one of the other brands designed for artwork. )
when doing 'realistic' artwork you dont outline anything.
watch the video before committing paint to paper. the hair is just a heap of daggers/lines in varying thicknesses and density of paint.
