Awareness or Visualization

Thoroughout the day, is it better to practice being aware of everything going on to increase senses, or to strengthen our imagination and visualization?

I think awareness would allow you to get more detail out of an LD. However strengthening internal visualization while awake may also strengthen detail when doing an LD.

Or should I split the time and devote time to each of them?

Improving both would be beneficial. During the day you can work on increasing the awareness of your senses, and at night you can practice visualization techniques. Good questions! :)
