fan club, nice.
it is a little bit of a long video, but it shows how long a sketch takes.... even a not very good one. That was sped up even.
I think this gets to the topic of self criticism that Jon brought up the other day, and my response on a tight sketch vs a loose sketch: http://boards.core77.com/viewtopic.php?f=27&t=28129
The sketch above is not that pretty, but it is loose, offers room for a little creative interpretation, and communicates an idea simply that can be used to have a collaborative conversation to get it to the next level. It isn't really a design, or even a flushed out concept, it is the visualization of a raw idea.
