I really like the effect of the water streaming down the sides of the hull, that is subtle and well done. And his color blending is outstanding. Have to admit that I'm now tempted to try a little cotton to represent flying spray in my next stormy ocean scene, but I'm not sure if it'll look as good in 1/700 as it does in 1/350.
The only thing I really don't like about using silicone for water, and why I stick to acrylic gel medium, is those weird-looking little pointy waves you always seem to get with silicone. There doesn't seem to be any good way around that, and to me that injects a vaguely cartoonish element into the overall display. But I'm anal that way ...
