A long time ago I converted a Otherworld Miniatures Giant Leech to a Grick (see concept art at bottom of the post). Now this was a long time ago and it broke about half a year ago when I seriously fumbled it.
So for 'finishing up' I grabbed all the pieces, reconstructed some of the (admittedly crappy) paintjob and added eeww-ey ooze to the base with crystal gel. I didn't fully repaint the mini, because that is not the point of 'finishing up'. If I keep updating paintjobs I will never get to minis that don't even have a paintjob yet.
