Whats next?

I know that I haven't gotten around to showing all of my collection of chose yet but i was wondering what I should look into next. as you have seen,

I have 1 Obliterator
1 Terminator lord
around 10 terminators
1Dreadnought
1 Demon Prince of Nurgle
1about 20 SCM's.
I also have 2 land raiders
1 predator tank which can be coveted to a rhino
1 rhino
2 squads of 7 plague marines,
10 berserkers
10  of raptor jump infantry.

so what should i get more of, i was thinking of making some more obliteraters or getting some more heavy supports. if i do get some more armor i will do a tutorial on how I'm going to magnetize and assemble it.

i also intend to get some more stuff up on what I already have by the end of the weekend
