You are a lot like me that way. My own personal flaw is that I love drawing the subject, but my backgrounds always lack by comparison. A suggestion would be to try drawing just backgrounds for a few days. Then try doing a full piece again to see how your backgrounds have improved and if you can integrate your skill at both into one piece.
Beautiful, the fur looks so lifelike,as does the color of the grass! The different colors look lovely and the proportions are great!
The only thing I'd change is the background- I think it's a bit crowded. I'd suggest either shifting the wolf down or making the sky a bit bigger to balance out the ground. But overall, this is a really cute piece! I love wolves too!
