Kovu is about five/six here as opposed to being three-ish in the movie. He's about the age Simba was in the second film. ZiraxChumvi design with altered TLK1 colors.

Mheetu is my design. He's four/five here. He's clearly a white lion as a ScarxSarafina cub with TLK1 colors.

I commissioned these guys from kashimusprime.
