Refining the Arms
Like the rest of the body, the arms will be based on the human photo reference. As before, it is important to
get the muscular quality of the arms while retaining their thin and sinewy appearance. This will be accom-
plished by keeping the muscle mass low and the fatty tissues concentrated in the undersides of the limbs, as
if they are being pulled by gravity. The following steps show the arms in progress.
1. Isolate the area for the bicep muscle with a mask. Using the Claytubes brush, stroke the bicep, taking
care to get the flow of the muscle correct from beneath the deltoids and pectoral muscles ( Figure 8-104 ).
2. Isolate the area for the triceps muscle with a mask ( Figure 8-105 ) . Using the Clay Tubes and Inflate
brushes, rough in the three heads of the triceps muscles. Don't get too specific at this time, we just want to
get the general form suggested. The arm anatomy, like the rest of the figure, is best developed in passes,
as you work around the figure ( Figure 8-106 ) .
