The faces are simply drawn and usually obscured with gags and strapping which is a loss for me - I like to see expressions. There's a suggestion here of a good-looking young man with a decent body but generally the figures lack this much character. The puffed out cheeks are the trademark of another fem-dom artist 'Emma', the distortion of a man's means of seduction being a very unsubtle female punishment. There are also interesting similarities to Franco's early style in the treatment of the background detail.
In fact these images are cropped from larger fem dom illustrations and although the creator is a man you'll be in no doubt about where his interests lie if you see the way he draws women. His art expresses self-abasement and submission rather than gay domination. There's an extensive blog of his work at Augustine's Art but don't expect to see man on man action. His Deviant Art page is entirely devoted to women.
