Great sculpt (Alan Carrasco, right?). The look you've chosen reminds me of the look of whales out in the 'deep blue sea', when there's a lot of light being filtered through a lot of water.
Thank you man, yes indeed at first i have decided to painting it black with a very little of dark blue, more similar to the real whale's flesh but the model it would be result too dark so i have choosed a fantasy skin.
