Drawing with fingerprints.
I did a trial of the full scale DNA pattern in fingerprints
I wasn't sure about the colours so I had a play around with them in Brushes
I then did half a gold DNA on a darker background but got stuck on the ladder rungs.
Here's half of one and the other half joined together.
I've decided in the final one to keep the bright colours but put them on a darker background. I like their fun neon glow and they'd be the find of thing I'd choose personally so I'll go with that :)
Time: 2 hours ish
