First off, I can say without doubt that you've gotten MUCH better at drawing Saria since you drew the other one. You did create an interesting lighting, very different and neat-looking. I also love her pose, the hair, and the way you drew the anatomy.

Now onto the less-fun stuff. The sunny effect of the lighting is very nice, butit needs to be softened. the way the light reflects off of her makes her look a bit like plastic. this is more evident in the leg, perhaps because the light source appears to be coming from above, in which case the leg wouldn't illuminate as much as her arm.

Also, her hands. they've improved immensely, but they look a little clawlike. remember on her left hand, that the middle finger is longer than the others.

Last problem: the background. The colors fit very well, but the circles/bubbles make it look like she's underwater. I would suggest some leaf or tree brushes, or if you want to stay this abstract some straight lines. If you have to keep the bubbles, I would suggest making them yellow rather than green, to make it seem like they're sun or something.

Anyway, you've improved a lot, and you continue to leap forward with every picture. I hope you'll consider these ideas as you do your next picture. I look forward to seeing it
