This is absolutely beautiful I can't wait for any type of relative release. Very impressive. This is how RS SHOULD had been.
One minor thing I would suggest though instead of making the dialogues be like that where you have a widescreen of sorts make it so they speak with you able to look around etc make it more realistic. Have some kind of dialogue box you can choose options from pop up at the right time. Maybe take this a step further have voice actors to assist and so your player can have a true voice.
