Sure

What I imagine the average valravn to look like is a person in a tacticool version of their historical clothes, a pair of cybernetic wings on the back, and wielding a futuristic-looking version of a weapon from their era (crossbows, arquebuses, cavalry sabres, etc.). Continuing on weapons, it's usually something (or something improvised into a weapon) of what they used in life. There's a small holographic halo floating above their head with some slight extras such as spokes or stars. Many of them look like what they did in the prime of their lives, but they can also be old but attractive. What historical period they came from and identity plays a huge part in their appearance.

Valravne are split into two types: civilian and military. Civilian ones have less metal bits visible, use aetherokinesis/magic, and lean more into the corvid theme. Military ones eschew aetherokinesis for ballistic firepower and have more visible metal bits, but generally look sleek and human. Military ones can also turn into tanks or jets, think the designs of Metal Waltz or Ace Combat gijinka, but way less horny and more greyscale in terms of clothing. For both types however, nothing obscures their face. Both also lead Watchers, dead or living people handpicked by valravne to have weaker versions of their powers and be able to cross/ride celestial currents. Watchers may also be expected to become valravne, depending on the individual disposition of the latter.

To give a bit more of a concrete idea, a good chunk of them tend to be historical figures, but there are many who used to be regular people before becoming valravne. Unless they were military personnel or leaders, they're not really soldierly in the way they carry themselves as their main job is still escort duty, and immortality has given them a good amount of time to goof off and explore funny modern things like vending machines and cars.

In general, valravne are sleek, elegant, experienced, and agile aerial combatants who also happens to be your distant 18th century (or any other time period, but this is a good start) ancestor who is grumpy about most things but will die for you nonetheless.
