This was the Vader commission pic I was working on for...ever. It was on 1 metre squared canvas and the blending drove me mad.
The colours in the pic (well, the red) isn't really the correct colour and you would not believe the amount of black acrylic I got through.
Said I'd upload it and so here it is.
*Edited in order to spell Vader correctly*
I've uploaded a photo showing Vader on my wall. Hopefully, it gives some idea of the size of it: [link]
