Regardless of your scanner, the colors you chose create with form an excellent contrast and help the image to come toward the viewer; the darker blue/purple/black(?) bg sets off the complementary golden tones of your wolf very nicely.

It's nice that you emphasized the intent to make a feline-wolf in your description, since you have created a nice hybrid that is neither truly wolf or great cat. I love it!

I do think there a some improvements to be made, partially in perspective and partially in composition.

Perspective:

the face and expression are actually pretty good - but the nose is on a different angel than the rest of the creature. the face looks as though it should have a three-quarter view, nearly, and that is a hard angle to work in. The tail also seems rather big compared to the head, although that could be deliberate and I wouldn't complain!

Try using a two-point perspective grid and boxing in the face shapes, then filling in the details, it may help. Info on perspective and 2pt perspective can be found here [link] here [link] and here [link]

Composition:

While the overall composition is pretty even throughout, you have a large space near the top, which became mostly background and then a large white frame. If, for example, the tail curved in a more dramatic arc, possibly moving outside the background frame, it would balance the composition more and provide a little more visual interest.

An easy way to see if your drawing has a balanced composition is to look at it in the mirror. I am always surprised by what I see when doing this!
