Great photos - thank you for posting them.
I was looking at an ostrich Alma at my local store last week. It is a gorgeous bag. The one I tried on was an off-black color - it was stunning.
What I like about Louis Vuitton ostrich pieces is that they put a perfect skin on each panel of the bag, including the bottom. I have an ostrich Birkin, and Hermes puts an almost bald piece of ostrich on the bottom of the bag - and just about every ostrich Birkin I have seen has been like that. I was very impressed that LV chose to not go that route and uses perfect pieces on the whole bag.
