Operation: Black Coach Rescue (Update 2)

Current status of my rescue Black Coach. I've got everything primed, the replacement wheel has been printed, and I've got started with painting the vampire and coffin!

The wheel printed rather well, but my green stuff sculpting was a bit lacking as you can see (Picture 2). Any suggestions on how I could smooth it out and make it seem more like the others? I wouldn't mind priming it again.
