I can relate to jimjamesjimmy
I have a 6d, a 24 f2.8 non IS, a 100 f2 and I recently went to Egypt!
Here's a photo.
I found that Egypt photos are tricky.
Firstly, the sky is always dusty, even a clear day is still kinda dusty.
Secondly, it's really really bright. Which means, everything is pretty bright and stuff can wash out and you need to raw it back into reality, with bits dark and bits light.
Thirdly, the "picture style" can help, like 'Landscape". Not in this case though.
When I view my photo, and view your photo, they both look "equally as bland" in terms of colours. However, I recall that during the trip, the photo I took is /exactly/ the way it really looked like in the day.
Sometimes the expectation of what you want it to look like, is nothing like what it looks like. This results in you having to 'raw' it waaaaaaaay more.
First attachment was raw'd by DPP
Second through LR4. Different settings though. (I just raw'd this one right now)
I now think the second photo is better :/ but the first one is more realistic and took less time to prepare
