I really like this, though I think it would be better if you placed it at the bottom left ( or your right) and then have the escalator go all the way up the shirt if you can. Other wise you should just do a different placement.
^Agreed... the crop of the image doesn't lend itself to making a nice t-shirt. The way it is, it feels like I went to the store, bought an inkjet iron-on, and printed out my own t-shirt using the 8.5X11 format. Use the whole shirt, have some directional movements.
