Take the White Scars, big thick black lines, difficult font to read ish and so on.
Any chance of a cleaner look?
Also the Terminators, how about two entries, one which is with land raiders and one without? Otherwise you end up with cheap terminators for air assault purposes. Although if you are out to change points 650 for termies plus raiders is a far better amount

Rebels wise, use those pdf aircraft! Navy assets are a bit much

Plus their are limitless proxies and utterly crap aircraft should have a place in Epic

The missile launchers aren't actually the 2nd ed models. They are very simple scratchbuilds. Just get any missile model, build a gantry (dead easy) and stick it in an emplacement. Those 2nd ed models are far too high tech and mobile! And are you sure about the name?

Bombards. Its the 1st ed model, there hasn't been another till 3rd ed.
The Heavy bolter goes so the FF comes down in comparison to the SG bombard and to help witht he %+ armour save increase.
Snipers. For difference I would stick with the original 1 sniper for 25 points. More variety isn't needed, and you have your fluff saying its Ogryns are remarkable. So 1 sniper for 25 and 2 ogryns for 50 differentiates and reinforces this.
Howitzers. You have costed them a bit cheap at 125 per battery. is this intentional or an error?
Stormhammer. Any reason the Heavy bolters were changed to Lascannon? They clearly aren't, hell they are a bit to small even to be Heavy bolters but I thought I would be generous.
The style of Epic has the explanation for high stats, so the Bolters small arms note should really stay. Or has it just been cut off with the notes section? For reference I wrote
Notes: Reinforced Armour, Thick Rear Armour, Walker, Damage Capacity 3. Critical Hit Effect: The Stormhammer’s considerable magazine explodes. It
is destroyed, and any units within 5cm of the model suffer a hit on a D6 roll of 6. The Cannons can shoot and be used to confer the Ignore Cover ability
to the unit’s firefight attacks.
Note on walker. This represents the additional tracks often fitted in the underside of the hull, taken from Chimera or Leman Russ vehicles. Left to run
freely they may be connected to the main drive shaft when operating in treacherous environments giving improved traction
Thudd guns, the stat line is deliberately slightly different to balance it more with the Rapier, but not so here?
So why are the Rough riders and Mortars removed? The mortars perform two functions that you may not have realised without playing the list. They strengthen the infantry companies but also shift some emphasis away from separate artillery formations that are the mainstay of the typical siege regiment. Though initially they started off as a Griffon replacement

Its one of the things that make the list different and they are possibly the 2nd easiest scratchbuild in Epic (3rd if you include the empty base Tau stealths) being just 1-3 mortars to a stand and each being a round bit of plastic with two more bits as legs with a couple of loader models.
Rough riders are absolutely vital. The army is just too slow moving otherwise. They are there as a mobile unit, nothing more, nothing less. Without them you may as well make scout cars a 2+ requirement.
