Hey there.
I am loving your work so far and excited to see your next updates, a critique I would wan't to suggest is for your R.t.G peace, I don't think the characters blend in but I don't think they stand out as much as they probably should, so I think darkening their immediate background would make them pop even more, I don't think it's necessary to see the destroyed buildings behind the characters or at least the rubble under their knees as much as the buildings and rubble you see above them, I think it would look a lot more 3 dimensional if statue was lit the same way it is now but, the immediate background behind the characters was darker giving the impression that they are standing farther away from the statue and the city.
Just my opinion of course I'm that experienced in composition myself.
Keep up the good work.
