Mirai wo Kudaki Cover WIP

UPDATE: So now they're colored and the lineart looks beautiful if I do say so myself XD still no background and I need to decide on the logo but I'm that much closer~

So this is the WIP of the cover of my manga which features the twins, Lucian and Mendel~
Very, very, VERY much a work in progress; super-sketchy, no actual logo, and I haven't even started on a background but I like how it looks so far ^^

Finished product:
