Akira Egawa really knows how to make some beautiful Karna art, definitely one of the best artists when it comes to the Son of the Sun God.
Seeing this picture, it really makes me wish we had a "Karna Alter" that'd be summoned as another Servant class, either as a Rider with his chariot (his design known as Botsu/Death Karna, that can be seen here https://www.zerochan.net/760449 could be used) or, even better, as an Archer with his bow Vijaya, for a potentially awesome archery duel with Arjuna.
