I think that unasked for critique is a bit irritating especially if I am in an irritated mood. My answer is likely to be "yes I could do that and then I would be like you eh?" or "why don't you try to understand what I did instead of telling me to do what you would do?"
But I do have some people who I am curious what they think of my work. They are open minded people and I am wondering if what is having an impact on me is having an impact on them as well.
