Hi, This is a cute pose of the wolf pup.
Here is a demo by Rose Baggs, I often refer to it, even though the dog is black and white it will give you some ideas.
and here is a WIP of a cat by Cravia she posted on her blog, you will have to stroll down to see the cat, but it will give you some ideas.
Check out the pastel library too, there are lots of demos there to look at.
I always go with my darkest darks first, and layer my lighter colors on top. You will find with velour that it is very hard to blend the pastels, you may want to find a different paper to start on, because it is very hard to make any corrections on velour.
As far as the background, I would paint colors to show hints of shapes but not actually trees, bushes, unless you want to go very detailed with the background.
hope this helped some.
