- Considering the usual use of PSDs (contract work, most of it is under some sort of NDA), online uploading tool makes this a bit worrisome. I would much prefer drag-and-drop offline solution, similar to Slicy app. That would fit into designers' workflow and we could see some improvements.

- Right now the "grading" areas are few, and somewhat questionable. Mostly questionable is the use of different fonts and font sizes. Many designs benefit from 5-6 different fonts, slightly varying in weight and sizes for best legibility. Some designs are only possible because of that. Much more meaningful insights would be, for instance, non-integer font sizes (23.989 instead of 24), or use of too many font families, opposed to just "fonts" (same family, different weights).
