Sure. The current generative models cannot produce good details, and the generated images are often low resolution (e,g. 64x64). In the paper, we tried to enhance the low res result by stealing the high res details from the original photo. But in general, there are not many things you can do.

On the other hand, in the recent years, we see dramatic improvement of image quality from these generative models. Overall I think this is a promising and exciting direction.
