More photoshop fun!

Today I took some pics of the girls and then worked with them on photoshop...I wanted to try out layering and gradient tools. I need to learn how to clean the edges up better after I cut the person out and lay in a background layer. Any suggestions on how to get the cut edge to be cleaner? I ended up using the smudge and blur tool to get a nicer edge...but I hope there is an easier way. Also, what do you think of the logo...I think it looks much cleaner than my signature.
