Well, to be absolutely honest, im kinda sneaky with painting by hand. Always afraid to put an extra stroke to "ruin everything" on my work, may be that is the reason why i like matte painting so much. So, here is my experiment to do something without photo reference and over painting every nut and bolt, took about 10 hours a piece, summary. Hope you'll like it.
And, as always, solly for my engrish.
