the first one would look great with a fisheye lens
quick edit in photoshop to produce this, its a fisheye effect (with less IQ of course) a real Fisheye would make it look much better, also a longer shutter and a smaller aperture would have helped allot
Depending on how much light there actually is, I would try setting your aperture at around f/11 and set your shutter speed to about 25 or 30 seconds. This should give you a very crisp and clear picture. Also, you NEED to use a tripod haha.
