well, you have black lines where parallel connections exist, rather than series.

and red lines where series connections exist, rather than parallel.

as for where to put nickel, i don't know if it's right or not.

there are a number of good threads about how to build packs that show interconnect patterns and methods
i don't have any links but if you search for threads with

in the title or first post, you'll find most of these threads.

and there's at least one thread about how not to build packs that show stuff you don't want to do.
