Ok, I was too quick with my last response. let me make a more thorough critique for you so that you understand better.
For the boudoir, i did a quick google search for you since you said you just started dabbling in it. Here are two VERY helpful links. Not just for boudoir, for photography in general.

One thing i suggest, now that you have a new camera, is to scan the flickr pool for your model.
What the heck, here you go: http://www.flickr.com/groups/canon450d/pool/
Here’s a portrait pic off that pool (again, using the same camera you use): http://www.flickr.com/photos/unaddicted/7708676280/in/pool-canon450d
Here’s a portrait off your portfolio: http://melissasuemullins.weebly.com/uploads/1/0/9/6/10961146/6397631_orig.jpg
Can you spot the difference? If you look in the tags you can even find out that they used a 50mm lense! VERY helpful.
Here’s another and in the comments they tell you the EXACT setup: http://www.flickr.com/photos/robrook/7611766466/in/pool-canon450d

I hope i made my point clear without sounding like a COMPLETE ass. My point is only that you HAVE the same equipment as these people do, the only difference is that they have better understanding/control of their camera. Everyone keeps saying it over and over again, when you are still in the early stages of learning you shouldn’t be opening up shop. Hopefully this was of SOME help.
Side note: i sincerely hope that linking those pics wasn’t taboo. I think the direct link credits the photogs…but if there’s an issue let me know.
