beautiful pic; i like how there is contrast between the large, rugged, strong, muscular guy, and the beautiful, elegand, slender (nicely shaped), and clever lady!
their face expressions are perfect...
i like how each one is ''reading'' each others mind (just like westwarren32 correctly stated below), and i like how they are waiting for the other person to make ''the first move''.
its a nice drawing, filled with many details, an interesting couple and alot of sexiness in the air.
the girl is amazing, and i love her beautiful face, her nicely shaped body, and her (awesome) cleavage.
great work, you should do more stuff like this.
keep up the great work!
