Wait a minute… That looks rad! I like how you made it like someone drew this. I would like to know more about how you did this! Either you could private message me or here in this topic, if its alright for you.

The sketchy style for this GFX is pretty neat, and I’ve not seen it much before. What can use improvement, though, is the lighting. The shadows on the hills are extremely janky and angular. The piece itself could also use a lot more contrast with the background, since the white of the figure to the left blends in quite a bit with the off-purple of the scenery behind them. Overall, not a bad start, but I strongly suggest looking into other GFX to see how they handled similar effects.
Amazing, the gfx you have made is so cool. The shadow, auroras and the light around the body is too cool.
I models the ground and positioned everything in blender, then I traced the characters with a sketchy white brush and finally I put some small effects on them. (this was a commission for a Dominus fighting game thing)
Dude, that looks legit love the whole sketch look! 
Looks amazing! Keep up the great work!
