Overtake project progress wip 1 (Patreon)

This is bit of a weird one. Someone bought art and then the artist ghosted them for over a year, and then I was asked to take the sketch and do what I can to finish it by the buyer. So here is my progress over the last two days ^^

Still struggling with the anatomy a bit. I am not sure what the original artist was thinking or planning with a lot of choices they made.
