I don't understand, why anyone would make such "critical" comments.
As you say you are a new member; so you may not (yet) understand the way the forum operates. When folk post their drawings like this one, they are also accepting critical advice to improve it. More so with AU and Own Designs we do have drawings that can be vastly improved from some input from more knowlegable members. If we consider how Ashleys designs has evolved it is both a compliment to his own interest to improve it plus the helpful advice.
