Oh this is perfect, I was just about to ask if there is something like that here because I do like redlining but I don't want to do those without being asked for anymore, so, perfect! I'll try to be gentle Lego
First of all, I like the lizard theme to the character design. I also like the details of the pants specifically, because that looks very plastic.
Now, the proportions you chose remind be a bit of one piece, with a very small head, long limbs and a small and slender torso. I tried to keep that and bring it to a bit more balance. Overall the movement would be a bit more natural if you give it a bit of a tilt or a twist around the waistline, but since you did not draw it like that, I tried to keep it straight too.

The shoulder region looks like you had trouble. If you look at a skeleton now, the shoulderjoint is real close to the chest, floating underneith the clavicles outer end. So the shoulders should be mit more in, part of the torso and less pointing out. Joints in general are a bit difficult to wrap the head around, which I would say is like that on her left ellbow and the knees - as long as the left (her left) foot is not supposed to be behind the right foot, the knee should be about the same height, slightly lower than the right one.
I like the thiccness of the thighs however where the legs go into the boots, they should be getting thinner because the ankle is the thinnest part of the lower leg. I made the feet just a bit smaller as they look really huge, but since that can be a part of the concept or style, I didn't change it much. the angles of the feet are good.
The tail looks a bit off, imagine how it's connected to her rear and how thick it has to be, so it looks like that at the pointy end. from there, you get a better idea of the curve it should have.

To the Torso-region: The pants are really nice especially on the upper part, but the lower part does not quite align to the hip. This is high level nagging, I know hips and butts are a pain in the ass to draw (har har), but you should always try to align at least the part where the pants are real close to the body.
I am not sure how the collar is supposed to look, so I made it so it would be kinda symmetrical. If it was meant to look asymetrical, my apologies.
Last one is more a question of taste. The cute face-to-head-ratio is based of how we percieve small children, and there the eyes are just below the midline of the head, which is already a BIG difference to the being above them like on adults. On your pic, it'S where the brows start, making the face really small on the head. Since the rest of the body makes her look very big with the long legs and big feet, I would maybe balance it out a bit more. But as I said, this is pure taste.
I hope this was more help- than painful ^^° Tell me to tone it down a notch if it's too much.
