Shadow Breath asleep

Okay. Since you opened critiques, I'll be very realistic with you.

First of all, let's start with the background. It's nice that you're trying, but the grass just looks like it's.. There. I see no real effect of three-dimensions, rather, because it is very flat.
The rock looks like a lump of gray with no texture what so ever. You may want to look up tutorials for that.
Also, the moon is never that close in the sky. I live out in the country and even then it's not that big.
The clouds are okay but could use some work.
Overall, the sky looks like a back drop with absolutely no depth.

Now, onto the, uh, wolf thingy.
First of all, paws do not work that way. The toes are not enormous like you have drawn here. Shoulders also don't work this way. It's just not possible. Most dogs don't have hair, but even then, it would not be this flat. Hair does not even work that way on a human being.
Next, wolf snouts aren't shaped like that. They're actually rather square, and the nose should be bigger than that.
If you're trying to be "realistic" with your ears, I would suggest making them less wide, and a little more pointed rather than rounded. The fur inside the ears also don't look like that.
Next, I would say that the tail looks very flat. There's no fur detail on it like the rest of the body where it isn't even entirely necessary (hind legs and on the top of the shoulder). If you want it to look like a furry tail, give it fur.
Lastly, the hind leg "under" the body. Paws do not work that way. Paw pads also don't look like that.

The shading that's only on the rock also takes away from everything else, because it's all flat coloured.
