Aside from the excellent use of light and contrast, the subject matter is indeed invoke a response from the viewer. Especially for members of the vore fetish community. The piece leads your eye around so you instinctively take in all the wonderful use of color and texture as any well executed artwork should.
The artist's concern about the use of slime is a valid one, because if one uses too much fluid effects it could take away from the overall impact of the work. However, here it does the piece justice and was very well done. When one notices a little spittle splashes on the other girls face just adds to the drama of the work, and radiates a sense of dread for the character as she realizes she is next.
Overall a great piece. The line work could have used some more variation, which could have been explored more around the hands and clothing, but it hardly takes away from the story this work tries to tell.
Thank you for creating this wonderful work of art!
