You definitely have lots of potential in your art, I can tell you that. With a little clean up, you can end up in Intermediate in no time!
A bit of advise first;
I suggest actually coloring any art that you do in. If you use the fill bucket it just looks sloppy and some parts will be uncolored. Trust me, I should know c: **I used to fail so hard at computer art, it hurt to look at anything I made xD**
Also, your wolf is a bit unproportional. Her whole body looks kind of squished, and the legs are a bit skinny. I suggest looking at a few wolf tutorials/actual wolves/etc. and getting a feel for the body form and all.
While you draw, you should make a base layer just for all the messy stuff; like the base body circles and other stuff. I always have three starting layers: A Background {The layer you start off with}, A Sketch {The circles and messy stuff}, and my Final Lines {Finished lines}.
It really helps to have some sort of base form to work off, whether you be drawing wolves, ponies, people, etc.
I'm getting a bit too deep into this, aren't I? xD I don't mean to ramble, I just knows how it feel to be sitting in front of the blank Oekaki page and wonder 'How the horsefeathers do I work this?' xD Hope it helped some c:
