Your words are more hateful by assuming too much. You don't even know how long it took. You can't ORDER someone to "step up their game." And a graduate may do as they please. It's a free world; you can't go around telling people what to do. Give constructive criticism, and give actual steps for people to follow. If that's the steps it takes for them to get that finished product, leave them be. As a person in the creative industry, I know that there's all manner of weird and whacky ways of approaching a task. It's all about getting the product exactly as you would like it.
