Help with selection of cocktail ottoman

I desperately need some design help with the selection of an ottoman to coordinate with a customized H&M Evening sofa in Antelope Nugget (you can find a photo of it on the photo index) and would be so very grateful for your ideas and suggestions. The width of the sofa is 91”, (actual sitting space is about 71” in length). The depth of the ottoman can be no more than 32”. These are my current choices (but I’m open to other suggestions):

The next hurdle of course is the cover selection…I plan to go with leather, but need to add some “pop” since our Evening sofa, Abbott lounger and Evening chair/ottoman are all covered in Antelope Nugget. Thanks for the help!
