You're off to a good start. I have one important correction, which is that you're playing the rhythm wrong on the dotted notes. That's on the third beat of every measure, in sixteenth notes it should be one-ee-and-UH, not one-ee-AND-uh, which is what you're playing. Do that first, and then work on keeping a steady beat. You can find the piece on YouTube if you want to hear what the rhythm sounds like.
