Welcome to the forum! ^^ I hope you have a long and happy career in lucids…
Well-- as far as lucid dreaming goes, there are many many techniques you can try!
Like WILD, MILD, WBTB… there’s alot!
Choosing a technique is a useful thing to do first:
[How to Choose Your Technique)
Mostly, as personal advice goes, time and practice are important-- a relaxed approach works well, as you will know you have a lucid eventually-- just in time as long as you think about it! ^^
Summoning dream characters can be fun-- as long as you have a good idea as to the personality of them, you can visualize them being there by closing your eyes and imagining they’d be there, or even opening a door and expecting. :D~ There are lots of threads about summoning that you could find…^^~ Making them have realistic personalities depends on if you’re making them IWL or not… if you are, it depend on you, if you’re summoning a random dream character (or a recurring one) it’ll depend more on your dream… ^^~
As for the creation of scenes? It depends… a certain area/place, certain peoples or actions?
It all becomes easier with time and practice, as I said! XD ^^~
Less detail might be easier to call up on first try, but it really repend from one person to anothe for how easy that is…
Calling up a new landscape is moderately easy for me at least ^^~
Hope that helped!
