For my last render Gates of time
I asked to 25 artists if I could use their work to integrate it some tell me no and 16 allowed me to use their picture.
BUT ALL of them told me thanks for ASKING
???? Yes, just for asking...
For me that totally normal to ask before using someone else work and even more here where we are between artists.
I was really surprised so after looking around on DA I understood that asking isn't the rule and I think that really sad for a community like DA.
