The first one is Ashlie drawn as Mercy from Overwatch.

The second is the one one to the right of the Mercy Ashlie. It's Ashlie dragging Nick away from the story @Rainydogco made called Instinct. (I know I spelled elimination wrong I'm just too tired to change it.)

The third is the one in the bottom left. It's from a a story called The Fight For Our Lives by @D3WYBird (you can see Nick there)

And the last one is just a chibi Ashlie. I think she looks cute :3
