One thing I have noticed (and this is just an observation) a number of the figures suffer from "Edith Swanneck Syndrome" and appear to have very long necks......
OK it could be worse - I spose it could be "Gladstone Small Syndrome" - see photo if you are not old enough to remember......
I have actually decapitated 5 figures out of 8 and cut their necks down before replacing their heads a little nearer their shoulders.....
Oh, I remember Gladstone very well! I've never stopped following international cricket since I was 6!
Greenstuff/ProCreate and patience is your friend in this matter
I find ProCreate easier to work with but use both depending on what I'm converting.
