Depends.
For characters, It doesn't take me too long to make a base, since I usually have my mind set on what I want to do. What really takes me time is a palette, and the detail. Those two things could average from 30-45 minutes for me. Right now I want to try and experiment with art styles and see what I can pull off, so that can leave me open to C&C rather then anything else since I want ways to improve.
I've yet to try out tilesets of any sort.
