To be honest, it's a little simple for my taste. But I believe that's what makes it a good piece. It's not too complex, so your eye knows where to focus. The majority of the detail is put into the cats, which I like. The proportion for the cats are very good as well, and the character's personalities are evident in the way the artist positioned them. My only regret is that it wasn't as blurry as it it. I think that if the lines were a little more sharpened and/or defined in the foreground, the sense of perspective would be greatly amplified. Overall, I believe this is a good piece.
Hm. Seems very nice. But the background is very distracting. It sort of eye-catching. It took myself a few moments to even notice the cats. I also think that the clouds seem way too low to the ground, making them seem like rocks.
Now about the cats, Stormfur's back seems to be casting too dark of a shadow, as well as Brooke's. Stormfur's shoulder looks sort of off and I think you should add a backbone/line thing (/shot xD) As far as Brooke goes, she looks great! She looks beautiful actually <3 I love the detail of the shoulder blades and the stripes. But the shadow problem still lurks.
The wind (i think that's what you're trying to show) looks a little misleading as well. Other than that, this looks beautiful!
Well first I find my 'special' bookmark paper (just some type of card stock or thick paper)and they you get the length you want...after that you print it out on the card stock or thick paper and BOOM your have your self a bookmark. It takes me about 3 days to edit the photo get the right size and print it out on the paper. I first would print the pic out on a normal paper just in case you mess up ^-^ enjoy and if you have further questions note me ^-^
