the camera angle is perfect.
the reason it doesn't feel right, is because :
1) Lighting and background. The Whole picture doesn't have an overall color theme, even though your fog matches the sky, it still doesnt exxactly fit the envirnment. Perhaps making the fog " x=0 and y=3000 " would give the fog a more overall effect to the terrain. Not only that but the mountians are very spiky and mishapped.
2) about the color theme, you have bright green grass here, dark green trees there, and
red buildings, and ugly tiles and then the blue fog/sky. Stick to a single color array ( for instance, ( yellow/ red/orange ) or ( blue/ black/ purple ). Or if you want to get really advanced, use contrasting color themes, such as ( blue / orange ), ( purple / Red ) etc...
