i always like those twilek girls, but man, this is steamy, passionate and sexy as heck! :D
i love the twilek's face, her toned body, her big boobs, and her long legs. also, her pose is perfect.
i've gotta say, her face is very detailed, with nice alien features, such as the lines on her cheeks, or the two ''flesh horns'' that exist on her head, and her helmet that covers the top of her head.
also she has an awesome face expression.
oh, and the other alien-girl is very sexy as well, yes; beautiful face, nice slender body, awesome pose.
also, both their skins look sweaty and shiny, which is a very good detail.
very nice work.
as for one more (funny) detail, i like the drawing of the death-star that exists in the communication panel, and the ''shocked'' trooper who is watching the girls having fun. (so cool!)
overall, its a very sexy, hot drawing of two smoking hot alien babes.
its a perfect drawing, keep up the great work, and please do more!
