What a cool concept. The text is very evocative and is nicely complimented by the format and images.
images
I think the images really carry the article though- which is fine- and they seem AI-generated. That is also fine, because they look good and you clearly put effort into making them work. The first one with the closet and the third in stasis are my favorite.
image 2: wocky emerging
The second image is cool, but the Jabberwocky is coming out of the wall. I know that they can be cramped between architectural features so that it could be coming out of the wall, and there's a curtain there, but it seems odd that there's a curtain on the wall that would just be blocking windows to the room next door.
To fix this, I think it would be a relatively simple edit to either remove the door and replace it with black space to make it seem like a wall around the corner, or just crop it out. This would make the curtains stand out less, since it could be to block windows or whatever, and if it's coming in through a window that would look cooler.
I'd also make the head turn to its right (towards the camera). This would make it a bit more creepy and make the right arm's weird bend make more sense if it's emerging in that direction, and it would also more clearly situate the head between the two arms. The left arm (the jabberwocky's left) right now looks like its coming out diagonally across the chest, which looks kind of silly.
sonic gif
The sonic pings gif seems sort of odd. I'm not sure what it's supposed to represent. From what I can tell, the idea is that it's a maze of rooms and the Jabberwocky is like, mapping out the area with the orange rings being the sonar of its pulses. But this is an overhead view (can juna do that if there's ceilings?) and the pings are just sort of in the background, not really bouncing off of anything.
Which is fine, this is a really hard concept to illustrate. But I still think the best move here is to cut the gif since the animation doesn't communicate much and can be distracting from reading an already pretty dense article (which isn't helped by the font- thank you dyslexia reading option). Alternatively, and please bear with me I know how this sounds, I think it could be interesting to see like an. analog horror thing. (BEAR WITH ME) where it looks like the camera map from FNAF (BEAR WITH ME) and there's a repeating orange sonar icon in the rooms. Alternatively, you could use Dark Echo for inspiration. It's a game from about like 10 years ago, here's a link to the trailer that shows what I'm talking about. Again, this would be really hard to make but could be worth it. Dark Echo Trailer
I probably couldn't make that, but it's a suggestion and if you don't feel up for that (I wouldn't) I would rather you just cut the gif. Besides all that, upvoted! Cool stuff.
