"1984 and We" Comparative assignment help?

Hey all,

Recently joined the forums in the hope that somebody here will be able to help me. As an IB student in the Diplomas program I need to do an oral presentation on 1984, and the topic I chose was to compare 1984 to We.
I have come up with the similarities, differences and such based on the story and some of the recurring themes myself, but I'm having difficulty in one aspect.

Would anybody be able to help me in comparing the literary technique aspect of the two novels? I already have that the narrative style is very different, but then I cannot find any other techniques or features to compare.
Maybe things such as the use of repetition, or imagery, or language, but I could use help in getting the refined down so that I have a clear understanding of how they are used in the 2 novels.

Any help would be greatly appreciated, as my oral presentation is due Monday. It needs to be 10 minutes longer, so the more ideas the better :)

Thanks in advance.
