They still look awesome though, as does this entire piece. Also, while I love the facial expression, the eyes look a bit awkward with those tiny irises and cascades of tears. I also love how closely this resembles Monika, but some of the proportions and lines could use a bit of improvement. With that, I feel like you hit the most important nails on the head. I also like the general pose and expression.
I feel like the shading at the palm is a bit odd on the left hand, and the left fingers are a bit too far apart or thin, but they still look great! I also feel like the arms could have been done a bit better but they still work.
I like how the hands are drawn with a thicker line width to indicate that they are closer to us, the viewers on the other side, and even leaving their window.
While this piece is not quite perfect, it hits the right nails on the head as I see it. This is a really neat idea, and I love how you decided to execute it.
