Waka> yeah, his standing in the reins the yellow thing is kind of a counter wieght/armor to the front heavy cow. I will be doing some thumbs soon though Ill focus more on wicker/clay/stone saddles, armor ect. than leather/metal stuff.
Today I did a bit of anatomy - a full study of the back bone, only done it from a front positon (ribs removed). I included my practices as I memorise the more complex pieces (the cervicals and here the T's and L's meet). I feel one or two more sessions like this and ill have it memorised... not sure what help it will be but it's fun to do.
