You did good on the ball! Nice shade of blue too!
Cute smiley, he looks quite happy!
Nice monster, have you thought to add the monster face elements to your blue ball after you change the color? Easy way to add dimension to your element..
I'd like to see you expand on the set. You could make a set around the monster and around the ball and smiley separately. Use the scope in each of the three set with a few other elements.
That I would really like to see!
Hotspots okay? You simply have to make sure they are or the set is not usable..
