I personally like an off to the side insert of the prey myself. But that's coming from the perspective of a mostly pred kind of guy and I always enjoying seeing the belly with nothing obscuring it after someone/ something gets swallowed.

I kinda like cut-aways, but I'm also a fan of internal panals too. I guess I'm just a fan of internal bellies overall

I like both ways the same. I even like just seeing the belly after the prey got swallowed when the belly does not show any sign of the prey inside.

Personally I prefer panel or separate image because I don't like things getting obscured when the hypothetical viewer should/could see something else there.

Overall it isn't much of a bother for me tho. It can be done well either way.

I prefer separate images for internals. Sometimes a picture can lend itself very well to a cutaway, but most times I feel it may complicate the picture or make it too busy. Generally, I find size plays a huge factor in whether or not I will like the cutaway: it's much easier to pull off that kind of technique with a larger pred and smaller prey.

I like cutaways next to a non cutaway cause i enjoy seeing how they fit tightly inside. A side panel doesnt contribute to that

I usually prefer there to be internal panels instead of cut-aways so I can see both the belly and the prey. But this is mostly my preference when I'm drawing. I don't mind either style.

I am more for separate internal panels, myself. I like seeing both the body in its' natural state but also a shot of what it's like inside. Saying that, I do like your anatomical accuracy in your cutaways.

I like both separate panels and whole separate images about what's going on inside, but I like them not to be shown very often. Part of my awe of someone being eaten is them disappearing, going away forever to somewhere nobody else can reach, and then tiny hints or just logic causing those who remain to briefly imagine what they're going through before forcing it from their minds because it's too terrible and hopeless to focus their sympathy on.
Actually, now I think whole separate pages for internals would do this for me the best, pages with panels only showing what someone inside is going through without any escapes to the outside even for the viewer until the page is turned. That encourages my favorite feeling of certain dooming unquestioning "now they're gone" in vore the most.

It depends on how much space it takes up for me... Cut-aways are always very nice, but when they're so small you can barely see the pred, a separate internal panel to the side is preferred, to see the details of the prey and the organ around them.

I don't mind either but, when it comes to internals, I also like non internal versions of the same image.

I think it really depends on the picture, but i prefer sub-panels or separate pictures.

I think cut-aways have often the problem of either making it seem like the creature is nothing but stomach space, or being too small to be usefull if keeping more realistic proportions. It can work, but it's more tricky to not go too far one way or the other.

Also, with a separate picture or sub-panel, it give the option of easily making the picture less obviously vore-oriented, which is nice for commissioned art that will be used everywhere.

I usually don't care either way. Depends on how it's done.
I really like that sketch you posted a little while back with just the internals showing directly on the belly.

I tend to prefer to do focused internal views in their own panels if I'm doing comics unless I'm short of space in which case a cutaway does the job, cutaways off to the side are preferred for single images as I have a hard time applying internal views on top of tums. More importantly I much prefer to see the tum from the outside in all it's adorable squirming glory />w>/ <3

With taking commissions I'm willing to do whatever's asked of me in that regard as best I can but the above is my personal preferences, I'm more fine without the internal view than with but I still do them now and again since I still find it fun to draw them myself.

I started off doing mostly cutaways but then switched to mostly panels
Cutaways are good at showing relative sizes but maybe I don't want to be constrained by that accuracy =w=;

I'm on the separate panel or image boat

You know, that's an interesting question. I suppose it depends on context and mood, whether the prey's unquestionable location is more important than the predator's position. A cutaway is good sometimes, an internal panel for others. Completely separate image feels like it loses some of the context, though, that you can gain with the other two.
