I understand your feeling and yeah it's really painful. It's something I would like we attempt plug the hole but it's very hard: I see two things ( I'm maybe wrong ):
It happens that most of the guys providing a lot of feedback here are usually pro and or students with a very good level. I don't know for the students but I know for sure that the pro are deep buried under a lot of work, especially there last months where a lot of feature film were getting completed.
Sometimes it's very hard to give advice and constructive feedback on beginner work without throwing generic ( But tremendously important ) comments that may seem offending for him. We can take Nathan comments for instance on your very own thread:
It may look like harsh, but I wouldn't really know what to say different. In fact I actually took a grab of your latest image and tried to do an overpaint, I stopped because it was too hard ( for me ) to produce something decent in a short time.
Again we are back to a time issue ( Which is short ), I decided to go back to my very own creature because I'm feeling I won't manage to end it up especially when also having to take care of the family
Let me know what do you honestly think. I'll redirect that post to Pascal, he may have some comments.
In the meantime I'll try to roam around a bit more!
