The panel structure is much neater, tidier, more dynamic than your previous work. I'd still suggest to work on cleaner depictions of the human form, I think that'd enhance it by a long shot.
You seem to be much better at backgrounds; the first thumbnail feels pretty spot on to me. I couldn't tell, until thumbnail 4, however, that it was a tentacle monster attacking, and why it was attacking. The lines in thumbnails 2, 3, 4 and 5 need distinguishing -- drawing it fast, in one stroke, could help it look steadier and less shaky -- and for something with a lot of action, there need to be clearer lines that distinguish.
Also, don't hesitate to use mid greys, perhaps by just doing lighter ink washes for parts that are not too light, or not too dark.
There's been one artist whom I've been following this Inktober, her username on Twitter is kilotango. She's been doing an entire series of single thumbnails with characters Tacey and Clay, her originals. The way she draws and colours things has been a particular inspiration to me of late, and I'd also like you to see what you can pick up from that.
