Oil painting

Hello! Here's an oil painting I have recently finished. I am trying to sell it on Trade Me with a $26 reserve! because the girl at the art supplies shop told me that Das canvases were rubbish and would warp over time, so I'm selling it with the title "Does anyone want it?" haha.

I don't actually like it that much to be honest, but it's a start. I bought a good quality canvas today and I'm going to recreate the dancer I drew (below) as an oil painting.
