I've put the first sheet of ocean in - the shallows. Much of this pale green-blue ocean will be covered by further layers of deep water away from the island, and a line of surf will be shown at the shoreline where the rocks meet the water, but for now this single sheet will suffice to show the shape of the sea and the land put back together now that I have finished working on the shape of the land mass. This image is turning out to be a bit of a hybrid of different styles. The sand is a pale version of Bogies sand, the rock is Dundjinni cliff, and the water is my favourite so far - Herwin Weilink.
I think its worth pointing out here that I never regard anything about a drawing as being finished until the whole drawing starts to pull together by means of a thousand different tweaks towards the end, so where you see things that don't really work all that well together right now, these will gradually be adjusted as I work through towards that point of completion. I don't worry about textures noticeably repeating themselves (as with the cliff texture in the landmass) because worrying about something that is due to be covered up almost entirely by the next layer to go on the land is a waste of time.
Also, I am familiar with the use of the word Layer in the Photoshop sense, although in CC3 these are called Sheets, so you will catch me using both, sometimes in the same sentence. I apologise if this is confusing.
