Thanks for the comments, you guys are great.
Jedi Alien 5 seems to be the figure most folk like, see attached picture for a breakdown. Red Faction Creeper figure from Gamestars is the base figure. Popped head, hands and feet. Cut pegs from arms and drill holes for Gha Nachkt hands. Cut off pegs for feet and realign for 90 degrees (so the figure can stand up, and not be on all 4s) and re-attach feet. Head is from StarWarsGeek's eCrater store. Paint, accessorize and there it is. I recycled the heads for Misc Alien Jedi 6 (Marvel Rhino bodies).
I also have included some copies of other customs I have tried to reproduce for practice.
I-Am-Boba-Fett- yes, I have been collecting Micronauts since the 1970's, I loved they were on the same scale as Star Wars figures! 1:18 for life...
