A huge huge sketchbook and studies thread: http://conceptart.org/forums/showthread.php?t=202251 It's awesome.
The big big TAD student work thread from first semester foundations.
Art on every page....
If you are interested in going to art school there are two things you need to look for:
1. What do the instructors works look like and what are their client lists and industry success credits?
2. What does the student work look like?
If both are strong you can be sure that you will improve whether you spend time with the faculty or your peers and having both means a better opportunity to be with great people and have great success on your own.
Hope to see you in class.
