I've seen quite a few colors done of this pic and this is by far the best. The color swatches are perfect. You actually made the drawing stand out by using more natural muted shades. The water turned out amazing as did the sky. I think you did an awesome job at making this look how it was intended. If I was to pick anything to change, I would say... darken the hair just a bit. It's too burnt sienna, when it should be more burnt umber. LOL but that's just my opinion as I like dark brunettes better. Well done.
