You can see this pic as a AU-lion king where Mufasa survives. So here we have an Adult Kion and Kopa interacting with their grandfather Mufasa. Kiara also exist in this AU but she is the oldest here so she would spend the most of the time with Simba I tried to give mufasa's mane bit of a greyish glow, giving him a slightly older appearance then in the movie. It's just a what if drawing so don't think to much of it.
Kion takes the most after Mufasa and is like him a big lion both are slightly build above average while Kopa is smaller and not as bulky as Kion and mufasa
I left out the mark on Kion legs because I personally think It's just mud or that stuf rafiki uses.
