The thing I don't like about KV's walls ( which to me I think kinda weird that I don't like) is that they look like they came from the same artist. They all seem to have the same style and seem to often share the same colour pallet, so I don't exactly get my attention pulled to one, then another and so on, I just kinda scan over it.
I myself don't like over contrasted piece and feel that it might be hiding stuff. I tend to see that alot on KV wall ( and other walls lately) and plenty of texture always seems to be layered as well and not just used on occasion. Style get addapted and turned into new style, but it seems like this style has stuck with kv for some time now.
Don't get me wrong, individually some of the pieces have some nice qualities, but as a battle wall and shared in a team, it does seem pretty bland and uninteresting.
