A FOGGY day in the Blue Mountains

Me and two friends headed up to the Blue mountains today and were met by fog, rain and chilly weather, but we persevered and got some images. Here are a few that I would like to get some feedback on...(PS I shot using the S5 Pro in F2 - slide film mode - for most of the day hence the colours are rather saturated and bright)
Contrast - I like the colours but am uncertain about the composition

I will have to reshoot this next time I get the chance but what do you think of the concept...I think it may be a bit soft

The 180mm Sigma got a bit of a work out with this being one of my favourites from that lens today

5 shot HDR using Photomattix3 - any tips as to how to get rid of the grey patch of sky and the burnt our upper cascades?
