Thanks to [author's] physical descriptions of his mother and the house servant, characters end [and?] events are presented with a clearer and less abstract evocation [?] of the narrator memories and recollections.
"Evocation" is 'way too fancy. You might try, eg, "summons"; while the "the" there mebbe unnecessary thereat
This servant has a tree-made [?] figure : “with no shape at all” and “apple”. The red and black colors evoke satan or hell so we have here a characterization of a [the?] gothic style women [s/b "woman"?].
(Sometimes the "the" is the theoretically thespian. Forgive me if I kid a little, Marie, but of course "a women" is kinda fishy))
Forgive thee me therein Marie but this is a toughie indeed. I had to call in my Better Half, who is much smarter than I, who supposed the servant must have carved the figure out of a tree. My interpretation however:
This servant has a tree-like figure, "with no shape at all," beside "apple" suggesting red and black colors evoking Satan or Hell; so we have here….."
Nonetheless Marie you write well, while you're to be congratulated for your determination and persistence
