It's mixed well. I might be tempted to say the drums are ovemixed, (to loud), or the bass is to loud, but it's to practice guitar as you say, you probably wouldn't want to pan things to much either, but I'd experiment with panning things just a few percent, to make it more realistic, as to how me hear this live with real instruments.
Please review others , this is how you will learn ... and others will learn from you. Welcome to the board.
