'I don't have a clue what this referencesheet say but I still love it! you two have clearly put alot of work and love into this world and this species because it clearly shows with the attention to detail in every aspect! =)
I just love how you've shown all the different kinds of horn these goat-mustlids can have=) I especially enjoy the detail with the older one gets the more intricate and rugged their horns get, which is a great way to show age on anthro characters =)

Thank you, we really appreciate it! :>

More translation, imperfect but it's a start:

"" Рога для саиров являются очень важной и глубоко личной частью тела, с которой связано
множество религиозных традиций, поэтому уход за ними зачастую занимает много времени
и усердия. С появлением рожек маленьких саиров крестят, и это событие считается вторым днем рождения. Различные украшения и резьба на рогах нередкое явление среди них.
Рога нельзя обрезать без согласия их обладателя, кроме определенных случаев. В обязательном порядке рога укорачиваются при поступлении на службу в армию, а некоторые делают эту процедуру для удобства в работе и повседневной жизни."

The horns of a Sair are considered a very important and personal part of the body and are associated with many religious traditions. They often put a lot of time and care into maintaining them.
Sairs are baptised when their horns first emerge and this is considered a second birthday. Decorating and carving their own horns is a common form of personal expression and style.
With the exception of military service and personal choice for convenience and safety in work and everyday life horns are rarely cut.

"Различные вариации формы рогов:"

Several examples of variation in the shape of their horns:

"Одни из самых распространенных украшений – обручальные кольца, что носят на правом роге, и ленточки различных цветов, которые часто завязывают на различные праздники."

Some common jewelry and decorations: Wedding rings are worn on the right horn and ribbons of different colors are often associated with various holidays.

"Иногда рога могут отрастать неправильно, что может привести к различным неудобствам и заболеваниям, вплоть до смерти."

Sometimes horns grow improperly, which can lead to inconvenience, disease and even death.

"Рога, направленные вперед, характерны для иностранцев, но могут также являться результатом мутации." "

Horns that are angled forward are often associated with foreigners but can also be the result of a mutation.

I think it's a quite good translation, thank you very much! :>

One would think the horns could be cut to prevent what happened to the owner of that skull, but perhaps there are things preventing that?
