Chris,
Thank you very much for your very attractive comments.
I always notice after uploaded it, after having drawn it. About some weak points of it. And I draw it more, add touches.
Repeating such a thing, a shelf of my studio became a graveyard of my pictures.
However, I think that I am not hopeless. It is my training period, for a while. Good time comes someday, I expect it.
David,
I always thank you for your replies!
