It's an amazing head no doubt you are seriously an amazing artist the only thing I think I could criticize would be the tears on the outside, I feel like the highlights are off or something makes those streams look less like water/tears maybe you could use some more blues on the darker sides to kind of compliment it and make it pop like water instead of how it just kind of merges on the skin and doesn't look as realistic(im not a color theory expert so take that bit of advice with a grain of salt) but that brings me to the next point of how the lips almost have a kind of hyper-realistic look whereas the teeth are super cartoonish and honestly that might be your style and if so it's super unique and looks good but for me personally it kinda creeps me out but yeah, either way, amazing work you're an extremely talented artist.
