Heres another tip.
If you are posting MASSIVE images, instead of using tags like that around them, type in the word "Big" right before it to make them say [BIGIMG], on both ends of the tag. This will shrink your images to a better size for veiwing.
The background is working well. Nice colour, slightly overwhelming though. The potential improvements on these shoots now would be to play with the lighting and shadowing. You have some harsh lighting and crisp shadows that you can work out into gradients.
All in all liking it. Im very picky and it sometimes make me sound rude, but these shots are well done. ;)
