Greetings, my fellow dawi!

So I'm a very recent dwarf player, who started to collect dwarfs about a week ago. Through some trading I managed to get a decently sized force already, and this army is built from models that I have at my disposal. Since this is my fist attempt at a dwarf army, I'm interested in hearing any tips you might have, no matter what they're about. Unit sizes, army composition, your favourite runes etc., feel free to lay it on me.

Here we go:

Lords
Dwarf Lord "Brandur Azultromm"
Rune armour (2x Runes of Iron, Rune of Stone)
Rune weapon (Master Rune of Snorri Spangelhelm, 2x Runes of Speed
Runic talisman (2x Runes of Warding, Rune of the Furnace)
shied
Oathstone
-goes with Ironbreakers

Heroes

Runesmith "Turek Skarrenruf"
Rune of Balance
Rune of Spellbreaking
shield
-goes with Ironbreakers

Master Engineer "Dâin Smokebeard"

So as you might've noticed I'm not a huge fan of the famous gunline, but I wanted to have a decent amount of shooting around with Thunderers, newly added Irondrakes and three artillery pieces.

The main gist of the army is to guard the center with the bulwark unit of Ironbreakers with Runesmith and Lord in there, which means the unit can also deal with foes like Chaos Warriors with the Forgefire and all that. Thunderers are there for the same reason of whittling down Greatswords, Knights and Chaos Warriors. Cannons would focus down any monsters, nasty units like Demigryphs, Skullcrushers and other nastyness. Organ gun shoots where ever it wants. Flanks are held by the warriors with the help of Thunderers.

The biggest problem I obviously have is that I have very few units and low miniature count. At some point I might replace some of the Warriors with Irondrakes or Longbeards, as well as consider subsituting Ironbreakers with Hammerers, but since I don't have any of those units, I'm stuck with these.

Any ideas? Pros and cons? I appreciate any wisdom any of you Longbeards may have.
