I looked at airships in detail and thought 'HUH. This this and this could really use some awesomeness.' So, I made a small list of what your's truly thinks could be improved on.
Crash Sites You have these many tonne aircraft full of coal, explosives, helium, weaponry and some crazy crystals just SMASH int the ground at full speed. Common, we could really use some goods, no? First, expositions. These could be calculated by by the amount of flammables your ship had. Sum the ammo stores the ship, and by that sum calculate the intensity of the flash, the fire, and how much junk flies in all directions. Then, take the sum of the coal and the long term flammables on you'r ship and use the number to generate the long term fire and the pillars of black smoke.
Pillars Of Black Smoke Right now the smoke form ships is short term and rather disappointing in my opinion. Why no make these pillars go all the way up to the sky-limit in expanding cones? Have these pillars partially cover the ships in it. Imagine the scorched back sky filled with this smoke, coming from ships, flying or crashed.
Scratches Rather weird that your ships come out of fights with these devastating holes, and a after a repair they look like they have just been puked out of the factory. I thought of adding cracks, paint peeling off, ripped decals and bent armor appearing on the ship with time.
Weapons Fire I am rather saddened with current weapons fire. For example, look at the Supendium Cannon. It fires magical-hover-crystals-that-penetrate-stone-walls-and-steel-hulls-frying-the-insides-of-the-strongest-ships. I would expect that shot to be a flaming fireball of light that lashes out of you'r ship and explodes on contact with a flash of pure epic and awesome. Canons should fire with a puff of smoke, and larger cannons should have a flash. Also sound: why don't bombs make the classic whistle sounds as they bring the enemy their doom?!
Give us more epicness!
Hmmm...I like some of these. Though scratches, I would imagine, are a pain to code in and get correct.
