looks great, I guess its this one. https://cdna.artstation.com/p/assets...jpg?1619191563
Looks really good pretty close resemblance to the original.
I think what you could focus on are those really sharp highlights, you can't really go too crazy when it comes to highlights on a piece like this, sharp highlights add the illusion that there are more details in the drawing than what it actually is, like what you have on the bottom of the character, so just go nuts with it.
And you could make the darks even darker, and more defined, would really make the character pop, and make the wings look like they are ripped apart from each-other, right now it looks like they are wrapped together with some rubber bands, I do the same thing myself, get to attached to a certain brush size.
I think Sam Lamont has a lot of magenta tones in there as well.
did a quick paintover to show what I mean
Sorry, don't mean to hijack your thread :P
It would probably look good to add some magenta to it with either overlay or multiply mode.
