I use your photo "old man of wall" for my still life drawing practice in A2 paper
[link] (my mother upload this in facebook, I will tell my mother to erase it if you don'y allow this)
I intend to submit this work as portfolio for university in my country, may I? I won't forget to credit you as the owner of the photo, but if you don't want to I will just keep this on my room
If somebody want to buy my this art, do you allow me to sell it?
