Good job! Don't worry if it doesn't come out right every time. What's important is that you can see mistakes that you make, and you're doing a crazy variety of poses, so you'll improve with every drawing. I also agree with Virmir, it's my favorite too.
Also! Keep playing around with tone, rather than being satisfied with pure black-and-white outlining! You seem to have knack for it. ((In addition to the fact it REALLY helps hide mistakes))
Hopefully you'll get your tail (and wrist) back in gear soon!
