OK first off you haven't told us anything about the game at all, try doing that. Some comments about the screens:
To be blunt i think the first 2 screens look terrible, they have low-res textures, with a mixture between low and mid poly models (e.g. Low poly tree, but mid poly fountain), i would advise making the really low poly stuff higher and more detailed, maybe make some different textures ,and definitely change the trees\bushes the textures make them look terrible.
I will say good work for completing a working demo, and try and consider these improvements.

. The overall brightness is a littlebit intense though.
