Would you mind some critique?

Not at all! I love critique :)

Well, and this is honestly, I do not know all that much about "Flareon" or anything like that.

But, the first two things that I thought when I looked at this were:
1. The neck is broken on this animal.
2. Hes got serious bodily function problems.

I know its harsh n everything, and the painting as a whole is beautiful with the colors n whatnot, but if you had moved the head a little bit differently or made it look like it was looking over its shoulder, and the fire tail... maybe moved the point where it attaches to the rear end a little more "up" towards its back, it might have looked a little easier on the eyes.

And here I thought you were going to mention that way-too-short leg. Flareon is a type of firey, fox-like creature from the series of pokemon video games and animations.

Now that you've pointed it out, I can totally see the problems with the tail. It kinda looks like it's pooping jets of fire D: For the head, it's supposed to be looking over it's shoulder (not the visible one, the shoulder on the other side). Do you have a suggestion how to make that clearer?

Yeah the tail first thing I thought was "damn that things passing some horrendous gas!"

As for the shoulder thing... maybe instead of making the whole thing profile you can tilt it to where you can see... the far side of the back as well as the main side that you see now.
That way ... you can kind of tilt everything to the right a bit and be able to see a bit of the other shoulder, that way we know its looking over the other shoulder instead of having an exorcist moment. XP
