A bit of a departure from your usual style. I think the proportions of the cat's anatomy are a little distorted and there seems to be no shadow, but overall a great piece - nice composition and incredible use of the gradient tool to add some depth to the picture. I would love to see this in colour and, like ~ARTek92, would happily pay good money for a print. In fact I'd consider buying several as xmas gifts for friends and family! (this may even make the frontpage!!!)
Everything just works so nicely together. The bubbles are carefully placed, and the cat is just plainly cute. The subtle gradient just adds the extra-portion of pepper to the image. It is clear that this is the material awesomeness is made of. I salute you, sir, for having created material which surpasses anything previous by lengths! Congratulations for having stepped up onto a whole new level in your artistic career. Bravo!
I don't know, I think you could have maybe put a little more thought into the gradiant. I mean, c'mon, really? That should have been a 50/90-20/20-0 easily. Also, your circles are obviously not as round as they could be had you bothered to use the ellipsis tool. And everyone knows cat's eyes are horizontal, NOT VERTICAL.
My mind doesn't seem to be able to handle the amount of awesomeness in this piece of art... So instead I'll be "tolerating" it... and brag about your ability to NOT make wallpapers with normal resolutions
