Welcome to EPZ Robert.
Isnt this a magnificent sight, Lake Louise, and perfectly framed by the restaurant windows!
Ive seen this shot many times, and its a challenging shot to take. Challenging because the outside exposure requirements are very different to those inside the room, and its possible to end up with a compromise, - which this shot is, - and thats not always a bad thing.
Thats because the sky and clouds are overexposed, though the inside of the room is not bad, and neither is most of the outside scene. The shot really calls for two exposures, one for outside, one for either inside, or a compromise as here, and then the two combined using the best of both. Exposure bracketing is a useful method you can program the camera for.
Your metering mode is set to multi segment, which will average the scene, and perhaps you have a spot metering mode you could have used to meter the outside, lock the exposure, then re compose?; or, using multi segmant, go close to the window, meter the outside scene, loch exposure, then come back and recompose and shoot. Either mode would have caused a darker interior, which could have been blended with a shot like this.
Either way, - theres some detail recoverable using the highlight tool in CS4 which Ive loaded in mods, - along with some different possibilities on cropping. I have also applied some sharpening, - you need to check you newly re sized and saved image for sharpness and apply a little more as needed.
A smaller aperture would have provided better front to back sharpness, - though to be honest it looks quite decent. This would have requited a higher ISO to go to say f/11.
A nice first upload, - hope to see more, and hopefully you can get something useful out of this feedback.
