Greetings!
I've just finished this Ral Partha oldie from my collection - ES54 Winged Panther.
I went for a naturalistic black panther look but with a bluish sheen to the highlights (a bit like you sometimes see in movies as they're prowling through the jungle!). The wing skin recesses are actually a really dark red/brown but you can't exactly see it on these pics.
Interestingly, the blue highlights seemed a lot bluer after I added the static grass to the base.
Thanks for looking!
