Looking through your images, I've found a couple that are slightly out of focus. As I've mentioned on another one it might be that you are attempting to hand hold your camera at a shutter speed that is just a little too slow for shooting without a tripod.
As for the orange cast, this can be taken out in post processing if it is not intentional. It could be avoided in the first place by adjusting your white balance in camera before taking the shot. Or...the white balance could be adjusted in post processing IF you shoot in RAW mode.
And wow! regarding your camera. I just checked the specs to see if it has RAW capability (I see that it does) and I like the sensor that they put in it. I have a Sony F707 as a backup and I really like it. Your camera looks like a fantastic point and shoot!
