Compliments are good. But you will know if your works are top notch if you are getting render requests.

For example I am a big fan of lundqvist and he is consistent with making new artwork almost everyday and he is superb especially with clothes folds on the body. I commented on some of his works asking for a render of my favorite video game and did that twice and I am until now hoping he would make one.

Passion is anger and love combined. So if it looks angry, give it some love!
