personally, i got a point and shoot that i use when my DLSR aint around (also helps for taking "notes" in school off of a whiteboard)
and i know that cybershot
i almost got it before i found my Pentax Z10
anyway, this shot aint bad, but its at a normal view, standing up, the camera at eye level.
try going up on a hill, or down on the ground, hell, get in the water if u want
second, the colors are a bit bland for my liking, as well as the huge overexposed blot that is the sun
try a higher f-number and to reduce the amount of light that comes in, if it doesnt black out the entire image, of course
also, your horizon is planted right in the middle of the frame, dead center
also kind of average for a sunset shot
look up the rule of thirds on google if you dont know about it, it does wonders for composition
still, a good starting shot man =P
keep it up
