Something I forgot: None of the Hrothgar exclusive hairstyles (guys and gals both) have highlights. Only the derplander one has them because that's the same for everyone.
I suppose they did this because hair colour and fur colour are linked and the "highlights" colour is used for patterns, but this also means compared to the rest of the Hrothgar the exclusive (and so far only) hair will always look a bit bland. The best would be to detach hair colour from fur colour alltogether, but if this isn't going to be possible for whatever technical reason, maybe consider including highlights for the hair regardless? At least as an option?
