Calla Lily Commission

Calla Lily Commission for my sister's friend's sister, who, as you may have guessed, likes calla lilies I love them too, and it was fun to draw with it's shading (and slight colour hues) and my mum saw it and this made her want to try soft pastel ^_^ Oh, also, expect another soft pastel flower on black paper soon, my mum asked for one...
Anyway, don't know how many hours, 5 max. I honestly lose track of time.
