#1: Nice, but maybe a bit plain overall. 6.5/10 #2: Good start, but a bit monochromatic... 7.5/10 #3: Looks nice and unique, but I had trouble finding the render to begin with. 7/10
I don't much like the first or third ones in particular. The first one has most of the face covered by that swirl and the text on it is fairly hard to read, though it does have good lighting. The third one has equally hard to read text. The lighting isn't bad but I don't much like the colors. The second one though, I really like. The focal point is clearly visible and easy to find, the lighting is great and the effects are really good too. The text on the second one is harder to read then any of the other ones, but you don't really notice it at first. My averaged rating for all three: 7.5/10
