not bad. I don't like the "glowing" of the light blue one..it just looks a bit odd man out.

The bag need a bit more work. It looks like you just grabbed some CVs and pushed it in...push it more so it looks like a bag, it looks more like a "cone" to me.

Plus - I think you really need to have Shadows. this one lacks some...the bag, some of the marbles...if there's shadows, it will look more realistic that it's on the funky shaders (which I like)...but right now it just looks flat.
