I liked it, but I think it'd better without that head near her feet. Mainly because, well, I believe the giantess would not let only his head out of her butt
I had the head there cause well, I'm a gorey type fan XD. But overall I normally wanna show some inclination of a small guy being under there, and I figured the head thing was a bit of a pun with pop goes the weasel so I figured why not.
