Just a few pictures from a hotel i checked into a week ago, trying to learn with out a tripod so some might be slightly angled.

I tried uploading but they came out grainy

Typically it's recommended to post under 10 in here if you want valuable feedback on individual photos. As far as overall suggestions go though, I'd say pay a little more attention to composition. A lot of these are crooked and have a very snapshotty feel. There's also a lack of a definitive point of focus in a lot of them. Exposure seems decent in a lot of them, but some have some very blown out highlights. Maybe pay attention to the white balance as well. First two look very blue to me.

I agree with DawnPatrol. Your white balance seems off, and your temperature seems too low. Try changing your white balance when you change lighting- even using auto white balance will give you more success.

If worst comes to worst, (it happens to all of us at some point) and you don't change your WB, use the photoshop eyedropper tool to adjust the balance until it looks more accurate, or adjust the temperature to be a bit warmer to get rid of the blue tint.

In general... take your ISO down a notch and use a tripod if you need to. Also, check your white balance, your lighting really seems to be far too warm or cool most of the time.
