The dream being out of focus and not being stable I think has to do with you being new to lucid dreaming. Give it some time and as you start to dream, make sure that you work on your stabilizations techniques such as rubbing your hands, looking around, feeling textures or just simply sitting down and waiting for the dream to stabilize. Once the dream is stabilized, you can shout "increase clarity" or focus and it should work.

And I recommend the WILD lucid dreaming method if you are planning on having a lucid dream everynight. You can also practice using the DILD method, but that is more like a chance thing to me, it comes more naturally to others. The WILD method can be scary as it involves the entering into the dream phase which can be hectic, hallucinative and fast paced.

Good luck.
