Not convinced that your background does your image justice, change it! This is just one way of many, done in Pixlr the free java based editing suite.
This method is a bit belt and braces but that is the nature of this editing suite... Photoshop, Paintshop pro and Gimp have far superior selection tools (which are very important for this particular challenge) but they are rather costly where pixlr is totally without cost :-)
playing and making mistakes is the only way to learn!
