I still think the anatomy needs work.
I've hired and worked with a bunch of Lego comics artists over the last decade or two. Believe me, your grasp of minifig anatomy is way better than a lot of the professionals I've art directed.
What really stands out to me is your staging. For some reason it's hard to find comics artists nowadays who want to do anything other than dull two-heads-talking-against-a-flat-background frames, but even in the frames where you're not going into super detail it's clear that you're thinking about the 3D space the characters are inhabiting and being deliberate about how you place the viewpoint within that space. It's one of those things that you wouldn't think was a rare quality, but it is.

That's as much as I do a lot of the time, although I'm doing the digital version.
If there's one thing I'd suggest for a next step, once you get them to this level you should go back in with the same sharpie to reinforce some of the lines. That'll help separate the object edges from the textures and add some line weight variation.
(If there's two things, I'd next suggest trying out some hard blacks to pop your characters and composition, but that's a much bigger commitment.)
