Thanks >~<

The small intestine has a fair amount of liquid in it, depending on where you’re looking. If it’s right past the stomach, the duodenum is actually where the really nasty digestive fluids are.
 
As for the coloration, it does look a bit watery… short of going crazy and putting particulate simulation in the fluid, just adding some slight opacity and some color might help the illusion. It’s not so bad when it’s on the walls, but the drips are where it’s noticeable.
 
That said, this still looks really good :)

@Percy Technic  
Ah, I see.

@Exedrus  
Which is why I like to do small renders and show friends it before I do the full render… most of the time I don’t get a chance to so I either end up rerendering or just leaving it :/.

@Percy Technic  
6 hours? Wow you are more determined than I am.

@Percy Technic  
Woah, wait, the rendering phase took 6hrs? O.o That’s a pretty big chunk of time.

@Exedrus  
Nah. you aren’t being that. I’m just really never happy with my work is all XP and I’m glad things are being said so I know what to do next time. I just hate re-rendering 6 hours of work each time.

@Percy Technic  
Aw, don’t be sorry. You’re doing things here that I haven’t seen done on this site before. It’s pretty impressive, and I think there’s a lot of potential. That’s why I’m throwing my opinions all over the place. XD I really hope I’m not being too overbearing.

@Exedrus  
Mh. if I think of another pic to do. I’ll make it super squishy~ and play with lighting and fluids more. Vore is still super new to me to make. sorry >~<

@Percy Technic  
More or less.
 
Tho, now that I get a second look at this, I’m noticing a fair bit of that sort of squishy shaping along the bottom of the passage. But it’s not to easy to see because a lot of it is in shadow. Might pay off to alter the lighting a little so that detail is a bit more apparent. The same might be true of the right side of the passage, which is the part that made me suggest adding in more fleshy/squishy-ness.

@Exedrus  
Ah. If I get around to making more pics like these at all. I’ll try that. my other one actually has liquid from the walls coming down and top down. I didn’t want this one to be as wet. So needs to be more foldy and squishy and more wet in well… the appropriate places?

Woah an actual full fluid render. That’s kinda a rarity on this site. :D
 
Also if you’re drawing the inside of an orifice, might want to make the walls curve/sag inward more. For example (warning: explicit) this image, shows a common stylization for these sorts of internal shots: the walls sort of bend inward forming lots of bumps that layer on top of each other. These are convenient because they add lots of potential for nice looking shading (as curved surfaces that can show off lots of soft/smooth shadows and specularities).
 
When it comes to the fluids, I’m not sure how you’re doing them, but it might pay off to make them stick to the walls more. And have dripping/running effects in addition to the fluid that collects at the bottom (which maybe should look a little dirtier?). That would make it feel more like the inside of a body to me…

@Pagan  
eh. I felt the pose was similar. but I didn’t know what else to have him in. maybe if I thought it as a corner coming up and he’s like peaking over that could of worked. but idk.

@Percy Technic  
It’s fine you’re still learning you’ll get better.
 
Have you noticed he always looks like he’s in the same position like he’s coming down and leveling out?

@Pagan  
Maybe I can bs and say…. eh there isn’t anything I can think up for a reason for why there is fluid. sorry

@Pagan  
Thought so. ughg. Still learning on this stuff and by the time I was told. It was already like… 5 hours in.

The fluid probably shouldn’t be here if this is the intestines.
 
Also the fluid just looks like water rather than anything that would be inside a body though you probably already knew that and there isn’t really a way to change it.
