Telling someone not to comment if they don't like your art is unwise, as it makes you look like you are close-minded and not open to constructive criticism.
I like vore, but there are problems with this piece. The anatomy is considerably troubled. I can understand when an artist gives their characters large breasts, I occasionally like them large too. This is DeviantArt, too, so I shouldn't be surprised to see breasts that are larger than the woman's head (and your heads seem to be quite small already, which only makes the effect worse), although these tend to bother me. If you're going to go that route, make them look good. Invest more detail into them than simply a bit of shading and areolae without nipples.
[link] You don't have to get into this level of detail, including things like the glands of montgomery, but the lack of... anything... in the background means the eyes are going to focus on the other details.
The naga's hands are poor, and the fact that they remain visible over the cross-section showing us Shantae draws attention to that. Also, Shantae's hands seem to be almost coming out of the cross section. It seems you were trying to create some three-dimensionality, and there is some shading to do that, but again, I have to draw attention to the very flat background.
On to the heads: The features look painted on, rather than three-dimensional, and Shantae's hair, on the left side (our right) of her head looks more like part of a helmet than flowing, organic hair. [link] Once again, just putting this out as an example of how to effectively communicate depth on a two-dimensional medium. The eyes appear recessed in the head, and the nose (which Shantae lacks) seems to protrude from the face.
Shantae's foot is horrible, looking nothing like an actual foot, and while I could link you an example of expertly-drawn feet, I feel like my actions might be interpreted as excessively mean already, but you did ask for critique, so that's what I'm giving.
There is more I could say, but I want you to know I don't hate this, or hate you. This is simply something we've seen plenty of already, and done better at that. Keep working. Improve. That's what I need to say.
About your first comment, I think that he said if you don't like gore don't comment. Just asking for critique contradicts what you said. Also, I think you were a bit harsh. Sure, it's not the best but it's also not the worst.
I understand now that I was somewhat harsh, but I am also not required to say anything nice, and in several notes we exchanged, the reason my critique was rejected was because I had nothing positive to say, which is not a valid reason for rejecting my critique.
I offered ways in which the artist could improve in my critique, but this was evidently insufficient to make up for what I had said.
I also would've considered it condescending to say 'This isn't the worst vore art I've seen' as if that could salve the hurt I caused, but you're right, this is far from the worst, and if I attempt to critique this again, I will try to showcase what the artist did right as well, because there are some things worth mentioning.
