Over sharpness may be your "style" and that is fair enough, but personally I dont like it. It is important that any art you create, you expect criticism... at the end of the day the most important thing of any kind of creative industry is how the product you create is received. People may disagree with your methods now, but you never know it could be a trend in the future. Vincent Van Gough wasn't appreciated until after he died, and now he's one of the artistic greats. My criticism may not appear to agree with your style, but at the end of the day opinion is just that.
