Lesson No.6 - Painting The Old Watertank

Started brushing in the colours of the watertank.  I only use a limited palette, so all my 5 colours were involved.  First, I made the tank nice and round with highlights and reflected light.  That's the easy part.  Next, the corrugations!  With a fine brush, "draw" the lines around the tank with a dark purple.  Remember to follow the contours of the tank.  Drag the dark down into the hollows between the ridges, following the colour of the tank you have already done (e.g. where it is a rusty colour, add a purple mix to make that area a dark rusty colour) and then do the highlights in the same manner.  It's a little involved, but with patience you'll get the hang of it.
