Do you ever feel like you get conflicting feedback on your work? One critique will tell you that you need to do more of something, and another will tell you that you need less of it?

I think it goes without saying, people have different opinions and find different things attractive. I tend to dislike a lot of criticism, for this reason. It's hard to know what will actually improve my work and what will just make it adhere to another person's preferences more.

At what point does criticism cross the line from being a helpful and constructive comment to just being a means to change (perhaps unnecessarily) what is already a valid way of rendering or writing something?
