I actually made this a little over a year ago and never posted it here, but with the return of Blue Bombin' today I figured now's as good a time as any.
So, without further ado, here it is.
I also made a "pixelated" version, but I'm not quite as happy with it.
[Edit] Holy crap! It looks like it's official now. Not only did they use it for the promotional spots for today's stream (Sept. 21, 2018 Mega Man 6 - Part 02), but it's now the series art on the video pages (formerly a stock image of Mega Man)!
