The Sigma is known for it's relativly strong vignetting. Try to
correct for edge fall off.
But I suspect the HDR step to be the reason. Tonemapping tries to use
the whole available histogram which is different for a pure sky
image, a pure snow image and a mixed one. Either try to stitch the
HDR images using hugin/nona or HDR after stitching...
