Dinosaur Triptych

This is a rough plan for a large triptych for some friends of mine. The main idea is to build the image up of large textured areas of colour, in a similar style to another recent painting of mine, Castelo dos Mouros, only in this case with a dinosaur being approached by a car coming out of a time tunnel. The cloud of dust being kicked up by the car you can see in this version probably won't be as dramatic and yellow - and I want to include some kind of vague purplish effect to hint at the disappearing time tunnel.
The picture will be made up of three big canvases, about 1.2m tall. It's not exactly huge but bigger than I'm used to working - so it's also a bit of an experiment for me. I'm looking forward to all the extra real estate for texturing though.
I originally conceived this composition as a single canvas, but I like the idea of the long neck being centered in the middle panel, while the main focus is still in the lower right.
For an idea of what I'm planning for the background, below is a picture of the Brisbane river from up at Kayes Rocks that I'm using as a reference. I'm not going for realism although I do intend for the colours to be a lot closer to the photo below (although the painting above is blued a bit because I took it in the sunlight and I don't know how to use my digital camera).
