Figure study from Grafit Studio Epic female poses reference pack.
Initially was study sketching in my sketchbook then decided to do a quick color render, had so much fun exploring Opal stone effects in PS.
Also uploaded the process gif here too.

Highly recommend my favourite reference source from Grafit Studio, Do check out their reference pack with such great quality images if you guys are interested. (PS. this is not a promo for Grafit studio, it was just purely a fun study smiley
