Help Por Favor

Here is one of my first ski edit's using the Nikon D5000. I like the camera, and got it for an extremely good price. But I have definitely noticed some of its issues and some things it lacks. Anyways, some critiqueing would be greatly appreciated.

Some things I realized about the video that maybe you all could provide some feedback on:
- Ghosting/ frame bending when clips were slow motioned:  the camera already does some ghosting right when you view the clips, but when I slow-mo them it increases. I disabled resample, which definitely helped. (I realize I slowed the clip at :45 down way to far)
- White Balance/ flickering: This is something I'm really stuck on. If I'm moving the D5000 through different light variations it changes the white balance and colors so much. I guess I want it to stay constant (I'm not really sure) I may need to change my cam settings around a bit so maybe some recommendations?

Thanks a lot for the help/ time taken.
+K to those with feedback =]
