Rikku-boy, people are talking about other Androids because he said he was thinking of doing an Android Pack.
While the Android Pack is a good idea, it has been attempted before (by Ice Man, I think) and... well... Let's just say it was never released. I'm not saying you won't do it, I'm just saying I hope you finish it.
As for the models, I think that the #19 model is pretty good. I'm not a modeller so I don't know much about it. The feet do look a little odd, though. #16 looks good. It's a nice start, but I suggest you listen to nuttzy, since he has made some of the best models this forum has seen and pretty much knows what he's doing. I'm basically saying nice work and keep it up.
Damn... I need to stop writing essays
