You also appear (to my eye) have a colour cast on the photos, a little bit of a play with the filters tool in PS (if you don't shoot RAW) or the whitebalance if you do would remove them. you could also add a touch of vibrance and satuation to help them pop a bit. Then there is the contrast, levels and curves tools... As I said it's a bit of a dark art.

The first and second are better though, a little more foreground in the first (maybe shoot a little lower, get some of the cornish flowers in the foreground) and the second I can't help thinking the people are too close to the edge (but then you would have trouble getting the rest in, it's always a hard decision).
Hopefully I don't sound like I'm ripping them apart, i'm not, I think they are pretty nice, however they need some nice post processing done to make what you have look better and a bit more experience to get the timing and composition right. I hope I haven't been too brutally honest.

EDIT: And I agree with theheyes, a wide angle lens is not brilliant for landscapes as such, it is brilliant at shooting foreground interest with the landscape in the background.

So yep, get down nice and low, fill the bottom of the scene with some cornish flowers and let the dramatic landscape let your eye wonder back.
For example:

Nice pointers Amp. Didn't think to re-sharpen the image after the downsize despite having been given that advice a while back. I've not intentionally put a colour cast on the photos, most likely just be the calibration on my monitor combined with my eye sight!
You say the UWE lense isn't ideal for landscapes - I've always kind of worked on the impression that the more you can get in the better. Atleast in the experience of my shots I've taken I've always prefered the wider shots. Would I be better served by shooting with a 30mm prime at an appropriate aperature?
Really liking that first shot, makes me wish I had had a tripod with me to get a longer exposure whilst there too, with how rough the sea was it would have ended up looking like mist in no time at all!
[quote="theheyes, post: 20178281"]but the point is not to take the shot that everybody else walks up and takes and that often you can create something out of nothing - even if it means looking like a prat in the process. :o
