Excavation site

Last painting. I past a lot of time on it. I worked on the composition and used what i learned in class and advices from a friend. Maybe few mistakes left but i think it's better than i did before (hope to).
I used the previous speed of the forerunner's towers to make them looking for some king of  forerunner excavation site.

Anyway, i'm back to studies now, i'll post some 3D finished works soon !
