It will be much better if You will give the sun light, other lights, and some objects. Also it will be good if You will do some texture work (in Egypt wasnt any grass!).

the file is .gz so it opens in winrar :S

i can't open it so just looking at your screenshot from bird's eye view, I'd say you need more stuff to hide behind. just a flat-out run to the flag and back is boring (look at face-capture).
