As I painter of this figure I like to hear critics I guess is the same for the sculptor, but in my personal opinion a critic should come next with a possible solution according with the person who do the critics, I mean, not all critics comment has to be negative and leave it there, I think is better first to say the critic and then a solution or possible solution in a positive way to fix what he consider a mistake.
Remember that this is a subjective art, cause all art is subjective (some people like it some others don't). Please next time that someone say a critic about a figure please also comment about a solution to fix what he consider an error.
