Got inspired to do this on my most recent playthrough, there's a moment when you emerge from the tunnels on tuchunka and see vegetation sprouting from the ancient ruins, an uplifting bit of music plays and I got to thinking what it might be like to see the Krogan rising to the challenge of overcoming their violent past in order to become a proud race once again.
EDIT* here's the uplifting bit of music I mentioned titled "Hope" [link]
thanks to the user who found it for me.
Also I will fix the darn baby krogan headplates, stop pestering me about it lol
Some time after the ending to ME3, the Krogan are gifted cloned Kakliosaurs by the salarians as a gesture of goodwill and a parade is held on Tuchunka to celebrate the curing of the genophage and a move towards more peaceful relations between the salarians/turians and Krogan.
Wrex is holding his kid named after Mordin while the salarian scientist who cloned the kakliosaurs walks alongside Primarch Victus. Grunt leads to the left with some members of Aralakh company and Eve is of course in the center because females are now running the show.
For anyone who doesn't remember what kakliosaurs are they were an animal species on Tuchunka that went extinct and there is a side quest on the citadel to give a kakliosaur skull to a salarian scientist for possible cloning/research purposes. There are also paintings of Krogan riding them in the underground tunnels, which is what I referenced when drawing them.
