Detail levels/smoothness in 3D printing

[Evil Eye]

I'm greatly interested in 3D printing, specifically in designing my own models to print (and hopefully share with the hobbysphere). I don't have a printer just yet, but I'm saving my money in the hopes of being able to acquire a good one- aiming for an Elegoo Saturn, unless anyone has any better recommendations.
Anyway, whilst I can't actually print anything yet, I do have Blender and a Wacom Cintiq pen display, and have been working on practicing 3D modelling. Recently I produced what I'd consider to be the first wholly original model I'm actually proud of- an alternate head for a Tyranid Warrior.

Spoiler

(For a sense of scale, the neck joint indent is 3mm in diameter to fit on a Warrior body)
Now, I have to say that for a relative novice I'm actually disproportionately proud of this. Sure it's a bit rough in spots but I feel like I managed to make it look unique and nicely detailed without falling into the trap of many 3D printed miniatures of going completely overboard with spikes and greebles. However, as I am a complete novice with 3D printing I am slightly concerned over whether the detail resolution is high enough. I used the Remesh command to the best of my abilities to avoid it looking chunky, but if you look up close at the mouth you can see the teeth are a touch on the crusty side.

Spoiler

However, that said, I'm also worried about working too hard to remove every last imperfection, as being as this is a Warrior head the details are pretty tiny, and I genuinely don't know if the roughness will even be visible in the final printed product.

So TLDR: Putting aside any minor undiscovered booboos/sculpting errors that need fixing (and of course the slicing, which I can't do until I get a printer anyway) would this be OK for printing, or would I need to smooth the rough spots out further?

Due to the way that Resin Printers print, I cannot see a way to orientate and support the model in such a way to get the teeth to print without them being ruined with supports. Splitting the lower jaw into a second piece would make the most sense.

In regards to the detail level, a correctly calibrated printer like the Saturn will have no trouble smashing a model like this out of the park.

Thanks! And yeah, that would probably be a good idea. Now I just have to work out how to do that in Blender- I know how to do so with low-poly models but with something as high-detail as this, it'll be, uh, interesting? But that's very reassuring anyway. I did cross-reference it with models people had shared and successfully printed and they actually seemed a bit "chunkier" than this, so presumably at this scale the facets are a complete non-issue for printing. As mentioned, despite understanding the basic principles behind resin printers pretty well, I've never actually used one so I was worried that every single microscopic imperfection in the model would be replicated, leaving me with a Warrior from Hive Fleet PS1 FMV Cutscene (singlehandedly responsible for destroying the Imperium's entire holo-game entertainment industry) but if the models I downloaded (and have seen printed by other hobbyists) are anything to go by I may have been overly paranoid.

I would suggest you join the Horus Heresy Discord Server fr Codewalruss.

You can find a link in the Age of Darkness subforum.

There are alot of people designing and printing stuff for the Warhammer scale.

There you should find alot of help for any question.

So update: I realize I've been going WAY overboard with poly density! I had initially planned on sculpting a Hierophant, started from the head an ended up with a PC-sweating 6 million polygons! Some advice from various sources got it down to like, barely 100K, and comparing it with the other 3D printed biotitan available (which I know is good as a friend printed the file) it has a similar detail density. Still needs a tongue, a proper neck joint and some general cleanup but anyway...
