I've whitened the snow and tweaked the contrast a bit. Better?

Yes, but now for my pet peeve, you see the bottom of the iceberg doesn't look level to me and neither does the little bit of the sea to left of the berg either - OK, I know I am a bit OCD about lines looking level, but not about being truly level as such, but looking level. Now I realise this effect may well be due to a sort of natural key-stoning effect of the berg lying at a receding angle to your lens and so it might be absolutely and geometrically correct, but still it looks a little bit wrong to me. So I would definitely try pulling the right side of the frame down a little and the way I would do it is as follows:
Duplicate the background layer twice, then increase the size of the image by a couple of inches in each direction. You will now have an empty border around the top two layers. Now turn on your grid lines (Ctrl+'). Now select all of the upper layer and hit Ctrl+t. Then grab the lower right corner handle as you hold down the Ctrl key and pull it straight down slightly until the bottom line of the berg looks right - not absolutely perfectly level, but just right to your eye. Then hit enter. Then on the middle layer, hold Ctrl and click the layer image, then select crop from the image drop down menu and flatten the image and which should then return back to its original dimensions, but now with a more level looking berg.
If you don't want to lose any of the sea and in fact gain a little on the left, then do all the above but instead pull the sky up slightly on the left.
Also if you ever do this and you need to stretch the shot to apparent level quite a lot, then the detail within the shot can become a bit elongated and thinner. So I would then suggest you can also stretch the image slightly wider again using your spare couple of empty inches around the frame to get it back looking as it should. You can do this by selecting the upper two layers simultaneously after you have level stretched the upper layer, then stretch them both sideways and then using the second layer to create your final crop selection as before and then flatten.
