The final lineart for this was actually ALMOST finished until the power source decided to become unstable enough to cut off and on again within 1 second.
And... since my usage on the tablet I have (darn) no habit of saving my work mid way... So,... yeah, I turned on my com again. Warily open the SAI file, and look, ooh... everything was back to sketch again..
.. after some serious cursing and swearing, maybe some uncontrollable hair pulling as well, I sighed, dropped my tablet pen, drink up my last drop of coffee, save the file as JPEG and posted it here, to honor all the 3 hours which I've just wasted in finishing the lineart.
Someone working in the power plant had to be spanked.
Oh well.. screw me.
