Pro artist opinion needed on my pencil sketch of a poster İ am working on?

You can skip this if you wanna get to the point, watch for the "*". İ am a pro 3d artist (specialized in animation and rigging), currently pursuing a career as a comic book artist, because İ am a huge fan of comic books and comic book related content (movies, cartoon and game), since İ was a little kid. And ever since İ have imagined my own characters and stories. So naturally İ wanna be a comic book artist, and release my comic books and it's media adaptation to into the market of fans where İ can earn, doing what İ love the most. So İ have currently running a campaign for this *.
And doing so İ am sketching live on streaming platforms. So my question is that, right now İ am in inking phase but what are your critiques and opinions on this art piece and what can be improve. Because this is the phase where İ wanna know if there are mistakes, so the poster turnout to be great. Please let me know...
