I love it. but I'd put the sandman below and to the left. (Maybe you were already going to do that, but just in case, I thought it should be said) Other than that, I wouldn't change anyhting. Just finish it.
oh, the only thing i would do to change it would add a solid cloud around the boy with the sand ghost things.. but its up to you, i weould buy it as is
I like the wizard lower like on the left but the boy & monsters (keep the dots!) seem a bit too close to the collar in that one, so I like placement on the right one.
Awesome design, 5! Too bad you chucked the chocolate with orange one (otherwise it'd be 5$)
i love the kid + dreams floating around, + would like to see it the bigger/focus of the shirt. don't know about the sandman guy though... i would like to see if they could do glitter print for the dreams! make it stand out more... a cute kids design!
