kinda fun in parts, but I won't return
I like the twist on the tired dress-up genre.
The characters were kinda cool.
I first played 'very hard', after a while found the fact that I had to shift tiny dots annoying, then played easy.
To make it a fuller game, you should really have a button that checks for you whether you've done it correctly or not. Have all pieces check if they are within, say, 40 pixels of where they should be. Maybe have a bonus for if they're within, say, 25 or 10 pixels. When we click the button, it could say, 'x pieces correctly placed'. x pieces within 25 pixels! X pieces within 10 pixels! And maybe a little firework animation should play for if we've got them all roughly, within 25 or within 10. (better animations for if we've got them all in more exactly.)
I really think that hard/very hard should have false items. Keep the things we need to drag big - if I had difficulty with the dragging itself, I'm sure children would too.

It's a cool idea. Reminds me of
deedz.net/bandpicgame.php?roun d=newgame
(although that game assumes knowledge of Project Rockstar's band pics, it might inspire you).
Was kinda fun in parts, but I won't return in its current state. It's definitely something you should think about taking further forwards.
