hmm yeah the newer lighting seems better but still needs improvement.
heres an example of what you want to achieve....

(note in the above pic the only light posts used are alpha light posts and a single regular invis light post. )
can you see the ambiance of the village lighting? as that is what you really want to get to. is to have each area have its own type of lighting. cities to have a city lighting, water lighting for water, special tiberium areas for their colors and so on.
keep working. you are for sure improving. just keep up the work effort and you will get better.
