Those weren't as bad as I was expecting.
But it looks like your using the built in flash, if you can (have the funds) invest in an external flash, its going to make your night shots look 100x better once you get the hang of things.
Just remember to keep your ISO as low as possible, the more you bump it up the grainier your photos are going to be.
But of course you don't want your shutter speed to low or your subject is going to be blurry.
Also some faster prime lens's are key in low light situations, so low f/stop is what your looking for.
and Last, your angles aren't the best, never shoot from behind, you always wan't to see the front of your subject (no one likes ass shots....well at least in sports)
But overall you'r photos will get better with time and practice, just keep at it.
