At least you realize it... Actually I think it's one of the most important instances of personal growth when you realize good criticism is worth more than even the best compliment. These days it's artistic growth that's my main goal, not pretty pictures, so I pounce on every kind of well-founded criticism like it's covered in chocolate.
Heh. You know who sent me the best critisism I ever got? Jozef Szekeres, the artist of the original Wavedancers series. He sent me a point-by-point list of criticism on one of my mermaid pictures on DA, not only pointing out what was wrong with it but also how I might correct it. That's the best kind of criticism you can ever get, especially as he is, of course, quite an accomplished artist himself.
Funny thing was, I was already halfway through a reply to his note before I realized who he was. Gave me quite a thrill, I can tell you!
