A good effort.
A couple of comments. Nice coloration on top, is the bottom all white? A little variation there is always good.
I would use a Mustad 37187 hook. http://www.terminaltackleco.com/prod_detail_list/66 This may be a discontinued hook so not all sellers carry them. Hook & Hackle lists them but doesn't carry them. Neither does JStockard. You can also try http://www.tackle-craft.com/product/ST-1734/37187/.

Hook clearance is really important as is having most of your hair on top of the fly. Without rubber legs, bass bugs can often lay over on their side.

My preference is to put more tail materials.
