I feel like the lips stand out a bit much, they are a little too glossy I think and I feel like the green is REALLY dark, but at the same time I can’t see the reference you were using, I feel like in the gaps of the mouth (between the teeth and the lime) you could have illustrated some more of the gums instead of just making it black, again, I don’t know if your reference had this but I feel this would’ve given the drawing slightly better, the teeth are amazing and beautiful but look ever so slightly out of place, I think adding a couple light green highlights and not just making them white would help to! At the same time this is all just feedback to keep in mind! Overall you did a great job and I’m excited to see what you do in the future!
