Here I do open a thread to receive opinions on my ring modeling tries. Below is my latest try to achieve something producible. I would like to hear sincere opinions, they may be very precious. There passed some time for learning the use of Moi -I do still consider myself a student though- and now there begin to appear some acceptable results I think. So share your thoughts and criticisms please! : -)
