Welcome to SC.com and congrats on your camera!
In terms of movement and ISO, I think there's nothing wrong with these shots. Some people would probably like to see the white balance a bit more neutral, others would probably like to keep it as is, to reflect the mood of the setting. If you do want to change it, you'd be best off developing the raw file instead of the jpeg, because raw gives you a lot more room for extreme edits before the image starts to fall apart.
One thing you might try is underexpose a little to prevent the highlights from blowing out as they did in shots 1 and 3. You'd probably need to develop the raw file and push the shadows a good bit to end up with a properly exposed shot.
