As a render, most especially for a beginner, it's not bad. Nice lighting. But, there are a blue-million naked cross-eyed Vickie pics in the galleries. Do something with her. For a headshot, show me an interesting face. You seem to have the basics down pretty well and I hope to see more from you. 1000x1000 is a bit (ok, not a bit... VERY) large for a headshot. Some people don't have a display that wide. Unless you have a pic with some very very interesting detailing going on (beyong Daz's lovely V3 texture), I'd suggest maybe no more than 800x800... The size you have it at now (465x419) allows me to see what needs to be seen and not get crazy with image size and bandwith.
