I'm with T`hinker`er on this one. If you want that green as your skin color, which I think look fine, you should consider finding an alternative scheme for the scales.
I know red is the complimentary color for green, but scheme is quite common I think. Maybe you coul try a bright yellow?
Of the scales color I like the earthy red best, but then you need to make to skin more tone downed and earthy as well. Plus the scales could use some highlights. Maybe a thin drybrush of bleached bone (nest to none paint on the brush).
I hope I've been to some help.
