Don Esteban has been roaming the local and international cosplay scene with his badass cosplay since 2013. In 2018 he won the title of Eurocosplay Champion for Austria with his Witcher cosplay. Detailed work with a variety of materials and being true to the original character design are his strengths, which is why he regularly joins renowned international competitions as a judge.

His cosplayer career began as a charity event, so every penny earned with cosplay is still being donated to charity.
