When drawing brick walls, start with the long horizontals first, then add the verticals in line on alternate rows followed by a second set of verticals in between this helps you focus rather than adding lines in the wrong place which is very easy to do. This is not a problem if you are working in pencil, although at times, you may wish to work in ink. Adding random colour shading to the wall creates a good effect.
Drawing wood can be achieved with simple lines, straight or curved and you can build detail if required by adding occasional eyes, bending the lines around them to suggest shape and grain.
Using lines and curves, plus overlap techniques you can create a complex looking image such as the De-clutter Mind Map
Building detail is far easier than it looks. My E-Books explain how you can draw anything you wish to with ease.
