I'm a day late to mark Osamu Tezuka's work, but then I've only found out about the anniversary only thanks to nanosesame's art post in the first place.
So, like the terribly original person, that I am I've decided to copy their inspiration and attempt to assemble some basic vector art in Inkscape (from a reference, but without tracing):
Black Jack, character and design property of Osamu Tezuka, recreated under fair use.
That fellow there is, surprisingly, not a glam rocker, but a heroic unlicensed medical practitioner, Black Jack. I might have made his hair look slightly fluffier and ridiculous than it should be, but only slightly.
The hair, my goodness, the hair on that man! (One of the reasons I didn't post the SVG, is that there was so much junk left over in spare layers...)
This was supposed to be a fairly quick sketch, but it's fair to say things got a bit hairy. If I'm ever going to do this again, I need to learn to simplify designs (or actually draw). The upside of this is that I've finally learned how control nodes work in Inkscape and got a lot of exercise with 'em!
And here's also something I've conjured out of the void with 3D Paint:

Just some "Tube Brush"-ing, "Sphere"(s), a "Hemisphere" and The Sun Terror is born.
WIP, originally with 20% more Terror.
Have a great week, folks!
