these are nice, very simple. they do give feelings of heat and cold. but what is their purpose?? will you develop these any more?? - JAG

no purpose, just sketch. i haven't got into detailed paintings yet even tho i would love to but time is against me since i have 5 studio classes at school but i'll show u my portfolio pieces once they're done. thx for the comment.
