UPDATED DESCRIPTION: I had this idea in my head for some time, what about giving this old fanart some photoshop love? Also I turned this into a wallpaper and gave it some additional symbols, I think it's an improvement, just in case here is the old link so you can see the difference:[link]
By the way, I have find an explanation of how such giant can fly through the sky, it uses a ramification of the antigravitational tecnology used by Yuri's flying disks, of course it's not as advanced as Yuri's tech, but it compensates in speed with heavy armour, also the MK2 is nuclear powered so in the unbelievable event of getting shot down it will create a massive explosion capable to damage even aircrafts in close proximity.
More art from the days of Red Alert 2, now those are heavy weapons, not just bombs but also an AP gatling gun, AA cannons and extra armor.
The work was done with markers, but I also applied some photoshop, still experimental, but I was happy with the result at that time,hmmm, maybe I should buy markers, they are better than pencils anyway.
