If any artist would be kind enough to supply one, I'd like a sigatar that looks like the following

Gender: Male
Race: Human
Clothing: Black plate mail and a dark red great helm that looks like this one.
Equipment: Longsword with a red hilt
Pose: Riding a white horse, holding sword above head.

As its going in the signature, feel free to make it whatever size you like.

Thanks in advance!
