animating those wings surely wont be easy, as a base i took a gargolyle sprite from FE8
pegasus knights will use swords and wyvern riders will use axes, to complete the weapon triangle in flying units, sky soldiers will use lances
on promotion pegasus knights and wyvern riders will get the capacity to use lances , but the sky soldiers promotion will get bows instead, however they will have lower movility than pegasus and wyverns

unless i decide to add more custom classes , when i finish this raven animation ,i will have sprites done for all classes for generic units, for heavy infantry i can just take something from the public repository and say that in armors that big anything can fit ,and for generic brigands there are already reptiles in the public repository
