Emperor of Novum

First big piece in quite a while I've spent a lot of time recently getting back into unreal and finally started learning blender so not done a lot of digital art.
This big green guy is the Emperor of Novum my Rome counterpart, a former slave that gained fame through gladiatorial combat becoming known for his strength and tactical ability's eventually becoming a citizen of Novum and gaining favour from the previous emperor who chose him as his successor.
I've been making my fantasy world for quite a while but I always have very loose rules in my head when I'm drawing so I've been trying to nail them down a bit.
