This is an interesting watch! The inner mouth camera shot of the character's leg getting licked was questionable ;) however the whole concept of the space dinosaur existing out in a water bubble in space was really cool! The follow up action scene was also really cool! But none of the people on the bridge are paying attention to this threat so I can only assume they're not aware of it?
These scenes don't make any sense without proper context so I can only wait to see if there is some sort of explanation before this scene or after it.
I enjoy the animation especially with Solveig burning through the vault door. General audiences will just say that the animation looks good and like it for being so complex and smooth, but there are a few animation errors here and there as well as a lightning fast timing you're going for which does work for a fast rescue scene, but may hurt the flow if you suddenly slow down at any point. Once again this requires the rest of the context but my advice is too keep up that pace if you're going to finish the whole thing.
The tone feels inconsistent as well? Showing the Dinosaur get half of it's face blown off then having people get sucked into space to showing aguy get buried in the ground Looney Tunes style with his eyes rolling around in his head and then the other guy gets vaporized to bone and muscle in a grim fashion? I don't know it was kind of jarring from point to point, but it might be what you're going for so ¯\_(ツ)_/¯
There was also a continuity error that bugged me when I watched this:
Why didn't the other area depressurize at 0:20? If there was a direct path to space that section would suck out too.
All in all this project has a lot of work behind it and while it is sort of worrying that this took 10 years to make, it seems that it all boils down to your motivation to work on something to show people and not having anyone to show it to. This isn't a waste of time if you finish it!
I would like to see it in it's entirety so I can understand what's going on in with the story and what the conclusion is. It's up to you what you do from here but I would suggest finishing it in the next year or so and not spend anymore time on it if you can't get it done by the fall next year 2023 but that's just some so in so's opinion so take it with however much salt your body can handle.
