Inertia is a property of matter.
edit: changed the shiny palette a lot, made the front face more front.
edit 2: changed the position of a tentacle.
edit 3: moved stuff around on the back to match the front. went blah on the shiny.
Quanyails - I love the pose and like the glowier-ness better, as it makes the spots seem actually glowing rather than painted on, as the other version's look to me. thank you for the crit; I tried to add the spikes in a less out-of-the-way place rather than the back, but it didn't really work.
V4LOVER - the backsprite seems awkward and a bit large, I'm not sure why. but I do agree that the front pose conveys the details best, even if it makes the backsprite strange. thank you for the crit, I tried to make it more front-facing.
Harry.Buxton - I love your pose, but the positions of the tentacles in the backsprite don't really match the positions in the front. the second-to-last (back) tentacle is down in the frontsprite but up in the backsprite. I do like your gender differences though.
epicparker - it looks a little big to me, especially the tentacles, which seem very thick. I'm not sure why. however you handle the membrane thingie very well, props for that! thank you for the crit, I did try to make the tentacles thinner.
User of Shadows - I like your pose, but the glowy things on the undersides of the tentacles make the backsprite seem... clustered? I'm not sure what the word for it is. I love the shiny colouring in general but dislike the shiny fins, as they seem to blend in to the body too much.
[rest... probably not tba later but I'll get to them sometime]
