Wow, beautiful! I like the blue one but I also really like the first one, the one you said didn't have enough contrast. Hang a picture of each of them up and leave them up for a week or so somewhere where you will walk by them and see them often. After walking by and viewing them both for a week, you should be able to pick the one that appeals most to you. It's a little trick that I've used from time to time when I can't make a decision about something. Usually by the end of a few days I find I'm drawn to one over the other and it might work for you.
Of course, if none of the options work, just send it to me and I'll take care of it. :lol:
