It is interesting to see how Thomas' style has improved from what looks like his earlier drawings. Especially the eyes, here when the girl is engaged in sex its hard to tell the difference between the iris and the schlera in certain scenes mostly because the line technique he uses to draw the eyes is too thick and messy. You can see in his later works that the eyes are much more clear, still using the line style seen here when the girls are engaged in sex, but more refined. Also there are better use of lights reflecting off the surface of the eye in later works. All in all this is a great addition to the favourites and I thank you for uploading and translating.
