Feedback on mismatched bridesmaids dresses please!

My girls bought their dresses today and they each chose a dress that made them feel beautiful which I love, but I'd love some feedback. We were going for an ombre green effect, how did we do?

We were also planning for the bridesmaids to all have updos of some sort, and all will hold a matching colourful bouquet. I don't really care too much about them being too matchy matchy because they will be seated for pretty much the whole ceremony.

Note: the dress in the middle is the same dress! But it looks bluey-green-ish in some lights for some reason. TIA!
