This is fan made and not meant to be accurate to the anime at all, this was made for fun.

Eren sat on the grass with Mikasa sat on his lap happily. Levi was sat next to Hange with his usual grumpy look. Bertolt lying in the blanket enjoying the sun, Annie sat looking at the clouds while Reiner was sat on the edge of the blanket. Many others like Erwin were scattered around the picnic area. Despite peace mostly being restored and many titans disappearing everyone was still a little wary.

Hange: "This is lovely. So peaceful, not having to worry constantly about being eaten."
