I have a lot of legacy content that I'm on the fence about releasing, as they are much smaller pictures. [about 800x500]

I used to make my frames a lot smaller to reduce the render time from 15 minutes to about 60 seconds. (think of it as speed drawing..) I did this especially for some indie games contracts as they wanted to keep the file/download-size small and the habit stuck for a long time.

If you don't mind the smaller images I can show sketch sessions for days.
