Interesting, I just commented, and the it accepted my comment, but nothing showed up.  Must have said something wrong.  One more time.

I like the angle of the first one, but it looks a little clutter for some reason.
2 looks 'tourist-ty', but shows off the arc nicely.
Of these, I prefer the second.

(Actually I prefer double O 7, but I guess he's not in the running.)

please "tourist-ty"

i like both.

#2. 

My personal pet peeve on many B&W photos is the lack of contrast between the subject and fore/background.  O1 has great contrast with the sky, and the foreground looks good other than the bushes, but the bushes blend right into the rock, giving it that cluttered look. 

You've got your work cut out for you on editing that.  Problem is the features on the rock look like the shrubs.  Like the 2nd bush from the right - there are marks on the rocks behind it that look just like the leaves.  Also, about 1/3 of the way from the right there's streaks running down the rocks that almost looked like another bush at first glance. 

I do like the perspective in it though.  If the bushes weren't there to begin with, it'd be a fantastic shot.  The contrast of the rock with the sky behind and the sand before is great, those bushes just keep throwing me.  

Good angles on both.......kwsNI is right in my opinion about the contrast. The black and white can hinder the true depth and tones given by color....so you need to do a little adjustment in post editing...

In PS2 I go to Image -adjustments -shadow/highligh t..(make sure to expand the options in this box )......then you have a great set of tools to change the depht of tones thru this applacation. At least for me, this is an easy tool to get good results from.
