Rhiwargor Waterfall

Rhiwargor is a rather beautiful cascade of waterfalls pouring into the Lake Vyrnwy reservoir.

I have often found the waterfall rather difficult to shoot as getting the balance between the foreground and background right is quite tricky. Today I went for the balance the camera on the rock, press the self timer and hope for the best approach.

I have cropped a little of the foreground, given it a bit of a fiddle in Lightroom/Photoshop and put an old photo filter on it and then taken down the yellow colour balance a bit.

OK help needed is there a reason I cannot seem to get my pictures large, I have uploaded the full size file, ticked various large boxes but still to no avail. Does this look Large or largeish to anyone else? It is not something I tend to do often but there is some nice blue whiteness in the water which would be nice for folk to see.
