And most importantly, if you are going to criticize, do it constructively, without silly nitpicking and offensive remarks. If someone has less experience in drawing, that doesn't mean they are worse. Especially if the reason is age.
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
