I am a big fan of all Tolkien universe and many P. Jackson recreations,
Related to that, and Warhammer universe, i was willing to make my own giant 1/72 eagles (with or without riders).
Well.. 1/72 giant eagles are the same as 28mm GIant Eagles Not big trobuel here (just finding suitable stuff in ebay, and I was able to find cheap (around 8 eur/eagle) original GW minis from the 90´s
But elf riders is really not so easy.. I got some 15mm demonworld figures wich are very nice elves in faces and torsos.. I just had to make some conversion with Zvezda russian to get a nice 1/72 Wood elf female Eagle Warrior
I also prepare some light elfe horsemen.. One of the figure does not even need conversion( legs long) enough) He matches good with 18mm eureka wood elves (almost 1/72 scale..)
