I struggle with all of them. Dialogue is my strongest aspect right now and I'm trying to not use it as a crutch so much. It seems that I skimp over stuff like setting and describing the scene. I just don't know how to do it and no one has really told me how to do it, so I've been stumbling in the dark. I feel like I'm getting better, and slowly gaining back my confidence, but it's going to be a long while before I can say that my description isn't lacking.
