Adzerak's book o' sketches

[TNiznet]

Nice work dude, my only critique is to spend more time on those Loomis construction, they look a bit rushed and the proportional flaws shows in your more developed faces, remember that eyes are about halfway in between the top of the head and chin, your eyes rest just about at the distance of where the eyebrow should sit. Pay careful attention to the proportions, you probably already know this but since I noticed it lacking in the heads, the nose is halfway between the eyebrows and chin, halfway between the nose and brows are the end of the eye sockets, half way between the end of sockets and eyebrows is the middle of the eye as well as where the keystone ends through the middle of the forehead, halfway below the nose and chin is the bottom of the lower lips, I usually just divide the bottom of the nose and chin in thirds, so first thirds is the bottom of the top lip or the divider of the lips, second third is where the shape of the top chin is attached to the plane that falls below the bottom lips and the last third will be your chin. Do a simple mark down of these proportions and align it next to Loomi's head illustration and you will see how it holds true =D. These aren't truly set and stone rules but merely suggestions, you can vary however you like but most heads fall in these proportions, lastly, the height of the bottom of nose to head is about the distance to find where your pit of the neck would be from the chin. Keep practicing dude, you will be great in no time.
