ASTROBOY!
Now and forever one of the best characters ever created. I have drawn Astroboy countless times and the above are but a sample.
This collection all started with the plush-style which was a new style I was trying out and that I applied to many characters (see here), however, it's the Astroboy flying in space that I really gravitate towards.
I'm sure there will be more Astroboy fan art in the future. Stay tuned...
