Very interesting pose. The character here is in a somewhat aggressive position (notably in the lower half), yet he gently handles a butterfly in his hand. It's a cool thing.
For the most part, anatomy is looking good. Only a few things I see here:

The hands look a little small. It might help to step back and check those before you put anything permanent down. As you can tell by my avatar, I have the same problem.

One more, the face is a tad crucked. Measure the distance from the eyes to the ears. His right (viewer's left) ear seems a lot further back than his left, which makes the face look a tad crucked. I also have this problem, though from my experience it's just practice to improve on this, since it's a big perspective thing (blah). One thing that might help is to draw a box around his head to help keep things lined up.

All in all, it's a steady improvement, and you did a good job on it. If you can afford it, I'd recommend getting other colors, and practising shading with the markers. After all, practice makes perfect, you know?

i was gonna do that but i only did the jeans i still have marking to put on his fur and shadings and if you didnt notice the [viewers left] eye is bigger then the other its wider open lol and the tails crooked but thank you so much nice to get someone to actually give advice normally its like looks greaat and im like THAT DOESNT HELP ME! D: lol so thanks ^^

I try to force myself to critique, as hard as it is. I hate it when I post something that is clearly flawed and everyone responds with "oh, that's nice".

Glad I could help.

I adore it!!!!
You did the coloring so well! Just when you said that you wouldn't.
You're always right when you don't listen. :P
And I love his hair!
Awesome job, Fay-chan. <3
