ORCHID PICS FROM SHOW

I went to an orchid show and captured the following pictures. I have been asked for some prints from friends, but I don't think they are necessarily good enough to hang on a wall. I would like some techniques to make them look more like art on a canvas. I think if I have a few of them printed on canvas, that would be nice. I am wanting opinions/critiques in general and also tips on how to make them look more like art. I have Photoshop CS4.

Post some pictures for critique.

Sorry, I had put in a link to the whole album of pictures, but here are links to individual pictures. Let me know if you can see these or if I should post them a different way.
