That's a good question. I actually like the way you draw characters. If there's one thing that pops out as perhaps needing variety, it might be the eyes? I actually went and browsed to make sure. A lot of what needed improvement a year ago, has been improved. I think you just need to focus on eyes, and perhaps faces in general?

I hid my last comment because I realized that I was giving you advice on something you didn't want advice on! Sorry about that. ^^;

For characters, one little thing I notice is the perspective seeming a bit misaligned on snouts/muzzles.

For example, on this image, it looks as though the muzzle is pointing more towards the viewer than the eyes would imply: http://www.furaffinity.net/view/24425839/

Here, it looks like the muzzle should be angled more upward because of the perspective on his eyelids: http://www.furaffinity.net/view/24498778/

On this image, the glasses are at a different angle than the snout: http://www.furaffinity.net/view/24435100/ . It looks as though the corner of his left lens is centered directly on the middle of his snout.

But that's just my amateur opinion!

Thank you, these are exactly the kinda pointers I need!

Anatomy seems good, all i can think is maybe play around with different styles to improve your current coloring/shading. It's very soft and i like that, but if you play with styles that emphasize contrast, colors it could help you color better to where you won't need the few black linings you use in some pics to separate body parts.
