for my cliff dwelling lizardmen XD not sure how it looks though or what else it needs, and yes I know other touchups are needed some people at my local game store suggested ideas such as a very light drybrush of yellow on the scales to give a shine or maybe varnishing their back since tzuki is a water god.
I have some Tzunki models too, and i use snot green, then blackwash, then another layer of snot green, then goblin green highlights, looks pretty sweet..
