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

Dreadnought

This is some progress on my first attempt at making a dreadnought. it is the one from the assault on black reach starter set, but I added the Nergle rot to his main body and gun arm.

the first two pics are just of him with a base coat of white.

these next three are after I painted him. I used a layer of rust covered by an olive green. I don't have any games workshop paints, I am using a brand called Testors.

he is about done now, i just need to finish the rot that is covering him and do something with the base. 

for the bases i was thinking of a swamp type look.
