First off, I must say great work with the fur shading! This is the first time I've ever seen you use this technique, and I must say with a bit more practice with it, I'm sure you'll be able to blow anyone away! The tail looks especially soft and natural, and so does the underbelly. The colored lineart also compliments it as well giving it a really realistic look to it. Just watch those stripes; It doesn't look like the texture showed up on them. Unless you didn't want it to...

I can't be too picky with the anatomy since you started this a while ago and I'm sure you know where your mistakes are with that. But the one thing that does stand out to me is that the arm grabbing the string seems thicker than the rest of the legs...

Anyways, great work~ The yellowed, warm background contrasts nicely with the reds, and the expression is absolutely priceless (: It makes a great icon for you as well, I see
I hope to see more work like this in the future~!

Wow, my first critique. Hopefully it's good...?

Anyhow, I love the concept of this picture. Overall, it's stunning, breath-taking and the colors you've used to create the mood of this picture is amazing in my opinion. The light warm colors in the background contrast nicely with the red and it allows the character to stand out from the background even though the colors aren't too contrasting. The strings are a nice touch too, it makes it seem as if the background itself has a lot of depth to it.

What I like about this picture that makes it somewhat different from your other artwork is that I really like the details you put in the fur; especially in the chest area. The tail area is also amazingly well done but slightly scribbly, but that's probably my own personal bias. I like the shading you used in this picture though, especially on the tail; with the colors of the background being bounced off the character.

I really like the pose of the character, especially the devious smile on October's face and the claws holding one of the strings, it makes the character seem that much intense. While the pose is great, the left forearm looks as if it's slightly bent out of shape and looks smaller then the right.

This entire picture is really well done, the shading is fabulous and I really like the texture you added to create a furry feel to the overall artwork. Great work!
