Great sky and waters. Not sure I'm buying the beard - looks too fake (shiny). And what are the 10 commandments doing in the scene? Moses packing them along just in case they might come in handy later? I do like that you have Moses with white hair (he was at least 80 at the time of the Exodus). I also like that the path through the sea is fairly wide - not just a trail. It must have been fairly wide for Pharaoh to think he could drive his army's chariots through it. The lighting is very nice.
A very ambitious editing project. Many things about this work well, although the hair completely overwhelms the tiny face, which appears to be that of a woman.
