Regu Satya: Lintas Gelap

Book cover illustration for Regu Satya series.
This time for the background I was heavily inspired by Western cartoon and graphic novel style... Something like in 'Ben 10' show... It doesn't have to be detailed drawn, and I like how it gives me a mute feeling, but at the same time it makes me wonder where the character will be going to? What is it at the end of the road?
