First, I took the Background, duplicated it, and then in blending mode chosen colour burn mode. It mad the forest much more...something.
That opened place for ever welcoming flare effect of sun rays cutting trough woods, and Carnotaurs head. I used gradient tool and after I just applied motion blur filter on it.
Somewhere along the way, I decided to flip the entire piece horizontally. In this point, things like fog, shadows, and more blending in of the dinosaur were ahead.
Here I added some fog to fern's, along with shadow. If you notice that dinosaur is now lighted properly. This is achieved again trough blending modes. I duplicated dinosaur and turned in screen mode for the upper layer, and then deleted with brush all logical places, where I supposed that light shouldn't be at.
Painting teeth's and eye was easiest part.
Final moves were adding the feel of wet skin, and painting evaporations. The wet skin was done, again, by duplicating major dinosaur layer and then, applied the plastic wrap on it, and subtle deleting of some parts, and leaving some parts behind, evaporation is paint job, took some time to get it properly done.
