Hahahaha, I think the reason 3/4 view is so appealing is because the facial structure is much more visible in that angle, and much easier to define. Its easier to define the brow ridge, the cheekbones, and the nose as well as the contour of the jaw. In front view its all so .... flat and chunky. ;( This is also people take selfies in 3/4 view. It is a much more pleasing angle to view.
This is so awesome! Probably the best head turn-around I have seen. A lot of the others I have been looking at have problems such as being vague on certain details (like the nose on a looking-up angle) or the character looks completely different at each angle. Your has none of these problems, everything is very clear.
I don't know how times people asked if they can use this and you got use to it by now, but this is out of courtesy. So, may I use this as reference, please? I mean... I am horrible at trying to draw a person's head in an angle whether they look up or down!
I'm glad you like it. I did see the other one going around that has like 3 times as many head poses as this, and I thought what a waste and how confusing. Its so unnecessary to have the same poses twice, just mirrored, and also camera angles from the top of the head. Though nice to see from a different camera angle, most people need a reference to start with a straight on camera angle.
I made this originally for myself, for practice, but then I thought, I'm sure there are a ton of people just like me who have a problem drawing faces at other than 3/4 view. I like how it turned out. In a lot of the images you can see how the nose obscures the eye as the head tilts.
I didn't really think it was necessary (because its usually covered with hair and/or is the pretty much an exact representation of the front with out the facial details.), but I can add it if you like. Are you looking for something like where the back of the skull or shadow of the skull would be?
