First cast. Not great, but I can work with these. I'll make another set, and pick the two that are least messed up.
A rare in-progress shot: a slug of green stuff, just prior to being smoothed and blended between the vent and the carapace.
Not too shabby...all vents have been blended into the carapace, and I even extended some of the vent pockmark patterns into the greenstuff.
