Adreaun - Dark Lord Demon Prince Character Design

First time making an art like this - kinda pressured but having fun at the same time.  
He's kinda unfinished and still making the details though.  

His name's Adreaun - from the Paralleled World to ours. Existing but unseen to the naked eye. He's long been hidden in the dark - for decades, unable to have a flesh, enough to really exist. But now, he is ready to take a walk out.Will you be his escort for an hour or two, yes?   


Gaaaah, I was slowly learning "guy's anatomy" here~
