A power node on the grid seems to be damaged, go and investigate ...
I normally paint everything in colour so this was probably my third (yet again failed) attempt at starting off in black and white and then adding colour. As the image quite clearly shows, I still don't have a clue on how to finish a painting in that order.
For those that know how to would apprecaite some feedback, I went about using an overlay layer and slowly added washes of colour. Maybe I just ran out of patience and should have kept adding washes, not sure.
Anyway despite the messed up colouring I liked the general image so posted it anyway.
Painted in Photoshop CS6 , Wacom Intuos.
P.S Just made a facebook account will start posting more sketches and step by steps over there. If you're interested.
