In retrospect I should have shot in black and white cause the colours are quite bland and don't add anything to the photos.
Yeah, black and white might be better, what with the bland colours. Although the colours give a nice cool feeling which are a quality in themselves.
I'd advise against ever shooting in black and white though, even if you're sure you want a black and white result. Photo editing software can typically do a better job than cameras do, and give you more control too. Then there's the flexibility of keeping it in colour if you so wish; you can always make a colour photograph black and white, but not the reverse.
PS you've got some nice shots in your flickr.
