Themes for etching

An idea of another etching I could do that tries to communicate a theme of the book - I'm showing a gross looking arm and leg with injection scars/marks

Been looking at Phillip Dvorak's work which I love - he works into his etchings with watercolour and gouache. Quick digital colour experiment:

Printing it out on cartridge paper to work into with gouache:

I think these turned out well. The printer in the studio is weird and makes the ink behave funny when printed so the background didn't work too well on the left one which is all gouache. Marker pen worked much better for the background as seen in the right version.
