What the setup and setting that you used for your images?
The images look oof/blur/grainy and not sharp to me.
It look also a bit too warm for me...
If you are taking the shots on your tripod, you should use your base ISO eg, Canon @ ISO 100, Nikon @ ISO 200. I can't advice further on the rest of your parameter since there is no EXIF in your images. You may also wish to work on your compositions...
Do remove your UV filter (if you have one on it) and turn of your IS or VR.
Shoot more, look forward for more shots from you.
BTW I dun understand your statement "aperture I set it to blub"?
Apeture have nothing to do with Bulb, Bulb is more on time/shutter value normally for long exposure shot...
