Well, Pirate decided to show me this thread for whatever reason and asked me to review some artists so I guess I'll oblige and look over the ones he looked over already.

A quick look at your Tenshi picture says that you don't have a solid grasp on the bones and outlying muscles that shape the human body. The signs are everywhere - the lack of knuckles or tendons in the hands, the lack of defined wrists, the lack of visible knees and tendons on the neck (skippable if your style prefers very slender necks), and the various features of the head, such as the nose and mouth not aligned with the way the skull should be shaping the head at its current angle (about 40-50 degrees to the right and 30 degrees down). The eyes are also a bit low on that skull.
Before fixing anything else, you need to get to work on being able to shape the more subtle parts of the human body. You have visible forearms, thighs and calves...and that's about it. A quick look at your own body (provided your build is similar to Tenko's) should reveal the parts of the body that need more definitive shape. The more (correct!) detail you have, the better.
I would also suggest not drawing clothes at the same time as drawing the body, which is what I assume happened because it looks like Tenko is sporting football gear around her shoulders. And those breasts are not shaped properly given that pose.
If you actually want some detailed critique, it would be wise to give examples of your preferred methods when you draw. What is the base you start out with? Do you use basic geometrical shapes? Do you just draw according to feel? The more information we have, the more advice we can provide, and the better the chances that something will come up to be of use to you.

Animal anatomy isn't my specialty as I've not laid eyes on many animals in reality, but your picture does indeed give off a very western-cartoonish feeling to it. Giving it a more 'eastern style' feeling would depend on what you plan to achieve with this drawing. Do you want this to be more animal than humanoid, or the other way around? Do you want to emphasize that this creature is from the east, or just that your drawing style of this sketch looks like it was influenced by eastern art?
Specifics, please. When drawings become more about style and creativity than realism, it helps to have as much information as possible to guide your sketch to what you want it to be.

Pirate hit upon several valid points but I'm too lazy to sort them out so I'll just rewrite the ones I agreed with, along with a few of my own observations.
Okuu's right shoulder is much thicker than her left. That armpit should be higher, which should in turn affect the location of the breasts. When the shoulder is raised, the breasts should be farther apart and slightly higher. And this is after you fix the general angle of the upper and lower torso.
To be specific, it looks like you are having trouble striking a common angle for Okuu. The head is at a 90 degree angle from the center, the shoulders are about 30 degrees off center, the upper torso is about 50 degrees off center, and the lower torso is about 10 degrees off. The head aside, the torso needs a bit of work.
The angle from which Okuu's right arm protrudes from her shoulder does not at all match what seems to be an arm with absolutely no foreshortening.
Cirno's a much bigger problem since she's not very defined and what I see right now does not at all match up with a human body. I would ask for a redraw on that since fixing it would take more work.
To everyone involved in the argument about how2art, just keep in mind that not everyone learns how to draw using the same steps or tutorials and such. Everyone has their Achilles' Heel when it comes to drawing, and sometimes it takes special methods to overcome it. But regardless, what you absolutely must need is attention to detail and a patient mind and heart. Your drawing only gets as far as you do.
