Very nice
3.jpg instantly reminded me of the west coast of New Zealand's south island, where the braided river from the Franz Josef glacier meets the sea (not the glacier itself). Maybe it wasn't like this, but all the parts of the scene work together to remind me of New Zealand.
1.jpg looks like a photo of Scotland in the thumbnail, but in the full size image I wish there were more detail in the terrain and some of the mid-ground textures look a bit too plain and 'fractal' (in the middle of the picture). The foreground, lighting and overall colour palette look great. I think the water looks like sediment-loaded water, which is nice, but not so much like ice.
