What is the most someone would pay for this painting?

I wanted to say you did a terrific job on it, but as far as how much would someone pay is very hard to answer. It all depends on the person buying it, and what they think it is worth. Some one who admired Gandhi very much might pay a small fortune for it, just to have it in their collection. While some one else may not even give it a second glance. All I can tell you is that you did a great job on it and I wish you all the luck in the world with your art. You are very talented.
