Please Say Something Nice

After almost eight months of graduate school, I have yet to find something to excel at. I often get feedback from essays or presentations that is lackluster at best. However, a professor for a course I am taking on visual culture wrote the following in the comments for a presentation I did:

"Throughout this class, I've been impressed with your ability to analyze pictures in terms of their formal properties and to understand how compositions work. This is a real strength."

Basically I think this means I should have taken some art history classes in undergrad and maybe looked for an image-based Masters instead of literature. She also said, "You have a very relaxed presentation manner, with a clear voice and good engagement with your audience." This may have been true for that particular presentation, as well as presentations I have done in the past at work or school, but as a whole for this program I have been terrible at presenting. I am currently writing an essay for this class, which involves analyzing a lot of images, I hope I do well on it.
