appreciate the thought, but i just had a buddy whose work got ripped off. someone took art off of his deviant page and sold it as their own. so for now, i'm keeping my art viewable, but relatively small.
depends on what you'd like... something like the universal ones (one character, simple bg, type) might run $125-$150...something like the star wars ones (lots of characters, more complex bg) would run $250-$300, but again, it all depends on the level of detail and # of characters. prices include high quality print.
