As a patterns of my drawings were used photographs from the Internet. Sorry for I did not include it in my question, I did not know it was important. So full of question is this =>
I have done a few drawn portraits of celebrities with photographs from the internet. I do not want to sell them. But my question is whether can I use these drawing portraits on my website, show them publicly as examples of my skills of drawing for acquiring customers for orders of portraits.
whether exposing the drowings on my website for advertising my drawing skills will not be considered as "profiteering"?
