I wish folks where more honest about what they say instead of just posting atta boy remarks. Some modelers, including myself, are not that great at certain things and pointing it out and giving advice usually will motivate someone to do better. If you give up or get all upset due to criticism, maybe you should not be posting pictures or showing your models in public venues.
And if someone is honest, most folks will attack the person for not being nice.
Best bet, just look and move on.
