If I could, I'd give it 4.5 stars, so I'm giving it 5 stars straight away as my review is about something quite minor but I think it would drastically improve the quality of the scenes and "their hotness".
The animation is great, like all their other animations. What happens is that the girl's movement feels too robotic when riding sometimes, I don't know if it's because of VaM's technical limitations or because of how the scene was made.
My suggestion is that the girl's movements are more circular and not "so linear", that is to say, when riding it would be good if she made a little hip movement, a grinding movement, I don't know if you know what I mean xD That would make the animation much more exciting. Currently I have to use the "SilverCircler" plugin to give that "natural feeling" to Alana's movements, which I personally think looks much better for the scene.
But well, it's just a small suggestion, the animation is great and as always, great work. I hope you'll keep it in mind for future scenes, and if not there's no problem, your scenes are still awesome!
