Well done!

Everything is so beautiful! It looks so pro!
I suggest you work a little on your artlines. It seems good at normal size, but if you zoom in you can see that it lacks of smoothness at some points (for example in the cuffs)

You could also either make the line disappear or make it a little more "dynamic".

You did an awesome job with the posture, an awesome job rendering the golden effect where there is gold, the anatomy is great, the posture, everything!
A lot of professional work aren't that good!

The composition is perfect! This illustration is so cool!

It is very good!! You did a great work!
Especially with the eyes, it is really difficult to make them realistic, give them volumes and lights, and gave them this moist aspect. And you nailed it!
The fur is also well done!!

The only things that must need a little more work are very little details you don't see first.

For example, the right ear is great, but the inside of the left ear seems to lack of something. I think maybe you should had some hair coming out in front of the inside shadow.
Maybe what does not work is that the inside of the left ear is not that detailled when the inside of the right ear is so detailled.

Also, there is some yellow reflects in the right eye but the left eye does not seems to have the same yellow reflect.

And in the brown part that comes out of the outer corner of the left eye, there is a strange orange-brownish dot (I don't know if you will see of what I am talking)

Anyway, great work! Realistic drawing is so difficult and you nailed it!
