i spent time resizing the pics, but i was having computer user issues, so i do apologize for the pic sizes and also please excuse the photography alot of the pics are blurry, but i think you can get the idea of what i am trying to achieve with my claywork for eyes.
the first step is to level the form vertically. pic 1
second step is to level the form horizontally. i do this by placing a level in front of the eyes lining up the front corner. pic 2
third step is to place a level horizontal line across the eye orbit. this is for two reasons. reason one, it helps line up the eye pupil, and secondly, the line at the back of the orbit is used as an idicator to keep me from dropping my top eyelid too low. pics 3, 4 and 5.
after my eye is set into the eye orbit, i roll a piece of clay into a blunt point about the size of a pen, and apply it to the front corner of the eye and laying it to the back of the eye, right on the edge of the white scleral band and iris. i then smooth the clay out onto the form. pics 6,7 and 8.
i roll out another blunt roll of clay for the upper lid about the size of a pen. i lay it on the top eyelid by pressing and blending the clay into the front of the eye and following the eye up and then angle it back towards the back of the eye making sure to go below the pencil line. i then pinch the excess clay off at the back of the eye and blend the clay to the form into the brow area. pics 9, 10, 11 and 12
the final steps are to check reference , kenneth bauman had an excellent series in the last breakthrough, and use a brush to sculpt the final shape you want for the expression you are trying to achieve. pics 13, 14 and 15.
there are so many variances in this business and this is just one of many. hopefully it will help. any other questions let me know and i will try to help if i can.
