One look at it and another at your username and i jumped "HE DID IT THIS IS AWESOME" --- Don't mind the stars so much still not used to it --- your style didn't change and that's good.it improved and that's impressive!! (where's the balloons (?))
the blends of colors are Awesome especially the suit! the Wrinkles & Folds are done well but still need to work on them more (the shirt sleeves and the pants)
The skin&hair are the most well colored the hair look full and love the textures adding more shine to it would be welcome too!
THE background love the idea of the shadow so much !! and the way it breaks from the floor to the wall is very good !!
OVerall: You proved you're and amazing artist .. the idea is creative and well made (still missing the balloon though ( ) your super star character is very lovely and cool ! Keep up hope i was fair and helped
