There are captivating features of this piece that hold the attention of the viewer, but I have to agree with Pete that I also would prefer to see more of an under-curve.

Incidentally, I notice that you have used Photobucket and that your thumbnails redirect us to that site. When you put the link to your photo in your posting, try clicking on 'IMG', at the bottom of the photo sharing menu. You'll notice that the link turns yellow and bears the word 'copied' briefly. Photobucket has then placed a link to the image on your clipboard, so if you simply paste it into your post (by pressing ALT and V), a link to the image will then be implanted into your post which opens the image within the post, rather than opening a new tab and redirecting the reader.
