I think a layman's opinion is in many ways an absolute must when it comes to artistic work. 99% of the audience for your work will be laymen, so saying 'you shouldn't comment if you can't do better' really doesn't make any sense.
On topic, I (as a proud layman) think this is a superb piece of work. In-game it still looks crisp and sharp, and tbh on par with many FH2 models, provided the metal and wood is dulled in a manner that makes it look like the metal on, say, the P38. Keep up the good work!
