I did shoot in RAW, since I do most of the time, is it best to leave the white balance on auto?
Different people have a different though process for this one. Some like to set the WB for the light their in (sunny, cloudy etc.) so they don't have to change it later. Others might take it step further and set a custom WB for the conditions they are in. Personally, I just leave it in AWB most of the time and do my white balance corrections (if needed) in Lightroom.
My VR was on. If I am shooting on a tripod, should I turn the VR off?
Yes. VR (or I.S. on a Canon) works via a gyroscopic effect, thus is has moving parts etc. But when the lens is perfectly still, that gyroscope will start to impart motion to the lens. So if you've been taking a bunch of shots (on a tripod) and they all seem much more blurry than they should...that is probably the culprit.
Of course, check the manual that came with the lens.
If you have any sharpness issues, cropping is just going to exacerbate the problem.
Also, have another picture I would like you to see if you don't mind. I tried to put it in this message but it said it was too big.
Cameras give us files big enough for printing. Displaying on a screen uses much lower resolution (about 300 PPI for print, about 72-100 for screen). So when you're going to upload for web viewing, it's best to resize the image first. Not only that, but apply some JPEG compression as well, so that the file size is nice and small.
I'm not sure what the limits are for upload to the site, that's kind of a newer feature. I often host photos on my own website, then just link/display them from there.
