Okay, for me it's this one:
It's from 2019 so it's definitely not my newest ones, and I think I managed to improve since then, especially with perspective and composition, but somehow this one stays my favourite. I think that's because while my other art my be better when it comes to technical skills, this one is the clearest about the direction I want to go with my drawings. It is my 'I GOT THIS' drawing haha cx I still go back to it when I feel like I'm lost and not making any progress.
Sooo what I like about it is the story-telling aspect! I think it's interesting, I managed to show my characters and their personalities as I wantetd them to be, I like the colours, and basically I'm proud of myself here hahah cx
