Vision What i really like in this wallpaper is the textures! They are so harmonized together, it makes the whole piece eye-catching! I also like the shiny characters, the shades give it a 3D Look, it reminds me of the game World of Goo! I would prefer the main character on the center with a smaller nose! The "a" on the background looks nice on the wooden texture!
Originality I can see some fresh ideas here! Even though the big cloud has sharp teeth and looks like the "bad guy" the fact he's wearing bandages makes it very cute and harmless! It's adorable!
Technique As i said, i love the shines on the elements combined with the textures. Also, the black strokes, look like they were painted with ink, give a cartoony and playful style!
A very interesting piece i would definitely use for my desktop background!
