residing evil- I don't like this phrase that much- where is it residing? How about 'presence of evil''?
allude- allude to
characters in Macbeth calls- subject/verb agreement
amoral- is this amoral or immoral- it strikes me as the latter
has its shares in the gloomy atmosphere- I'd change the verb- I'm not exactly sure what you aim to say, but do you mean something like 'adds'
Macbeth called- called on?
seeling night- spelling- you're not quoting here (I believe some texts do spell it 'seeling', but 'sealing' looks better to me, unless you put inverted commas around it too)
BTW, you seem to have a good appreciation of the play; the quotes you use seem well-chosen.
