How much leeway / technical wizardry do you have, Matt, such as putting a chain-axe on a loyalist WE, or morphing the legion symbols onto the shoulderpads? Forgive me if I throw out completely unrealistic ideas here - feel free to rein me in when I go overboard!
I can do putting Legion Symbols onto shoulder pads, add blood spatter and script. Basically, I'm alright with manipulating and adding to the painter images, but I don't think I can create things like chain axes in Photoshop. I can have a go but I don't think they will look very good.
1) World Eaters
They have not changed their armour from the Pre-Heresy white and blue, but they do use chain-axes.
This painter image comes courtesy of Moonsword. It doesn't have the WE legion symbol (not Khorne) on the shoulderpad, and ideally they should have a chain-axe rather than a bolter.
I'll redo it with a darker blue and add the legion symbol. I'll have a look at doing a chainaxe as well but I'll leave that till last. Are there any markings you would consider distinctive to the legion?
2) Emperor's Children
Their defining character, beyond their arrogance, is that they cling to pre-Heresy marks of armour, and remain the only legion to use the Aquila iconography.
This painter image again comes courtesy of Moonsword. It ticks most of the boxes, but if it can be improved, then please do.
I can try to make a clearer image. Anybody got an image of the Pre-Heresy Legion symbol?
3) Raven Guard
This could be tricky, as the post-Heresy Raven Guard are completely chaotic, with things that I would imagine are not anywhere on the painter. Thoughts?
Could do a blacked out scheme silhouette with the words 'Classified' pasted across it. Of course, that silhouette would not match your average marine's...
4) Word Bearers
They would keep the Pre-Heresy metal / grey armour, which is engraved with Lorgar's holy words. Thoughts?
Do you have an image of the scheme somewhere John? This is pretty much the only scheme I can't recall from memory. I think I can add script to the armour as well.
Quite similar to the HH version, but without the drag of superstition that holds back the Imperium they have higher tech - perhaps characteristic elements from the Tau? - and no need of purity seals. The Ultra 'U' would dominate, but could be winged.
What was the Shoulderpad trim during the Heresy? I'll have to think about how to incorporate some Tau stuff in, not sure how to do it subtly.
6) White Scars
I would defer to Phil on this one - would they stick with white or have Slaaneshi pastel elements incorporated into the colourscheme. I would also guess that they would be highly ornamented, given their aquisitive nature and love of bling.
Not sure how well I can add on the bling, as it were, but I'll see what I can do.
7) Space Wolves
They take the armour from defeated opponents both to replace battle damage and as trophies, so the occasional piece in a distinctive Ultramarine or Emperor's Children colour would be characterful - Think 13th company. They wear neck torcs to ward off the 'evils of sorcery', which they anoint in the blood of their enemies, so the grey chest armour is eternally splattered in dried blood. Spikes and horns seem to just magically appear as soon as a legion falls to chaos but perhaps not the Khorney bunny ears, which might be a step too far.
If I can find a good image of a torc, I'll see if I can add it in. Should be easy otherwise.
8) Thousand Sons
They keep the pre-Heresy red armour, with what I always think of as an Egyptian theme. See the excellent artwork that has been done for the legion in the artwork thread. Note that this will probably be really difficult to do on the painter!
Don't know how much I can do for these guys in terms of Egyptian styling.
9) Blood Angels
Corroded, mottled from red to rusted brown, yellow or even green in patches or streaks. Pre-Heresy they would probably love jump packs, but the post-heresy Blight-drone jump packs would probably be beyond the painter's abilities. Regarding the legion symbol, pre-Heresy it could be three blood drops, which morph post-Heresy into a stylised version of Nurgle's three circle chaos symbol?
Should be all good to do, barring blight drone jump packs.
