It looks for me more like Tomb Kings equivalent rather than Chaos, but who cares that? Sculpting is great! If I was strictly obeying the background and feel of warhammer (but I am not) I would say that this has nothing to do with the tzeentch deamon prince but hey that is not the point! I like egyptian culture and I think you did a great work...but as an old warhammer player I can say : Less Egyptian more Warhammer ;)
