It looks ok, but the smell is another thing if its really offensive. I rinse my weed in fresh saltwater after collecting and give it a quick run in a lettuce dryer or give it a good shake, then wrap it in kitchen towels and then wrap this in glad wrap if I am going to store it for a while. If its only for a day or so I still use the kitchen towel but wrap in a semi dry tea towel (only just wet) and it is always usable.
I try and separate any weed that looks brown, a bit dodgy, or slimy before storing.
