A sample of a drawing printed on a teeshirt. Any ideas on where I could sell such an item would be welcome..
 

Here are some more light grey and black fibre tip sketches. Using a light grey as a 'wash' it's easier to block in large areas of shadow without the need for crosshatching. The black line is used to put an accent on detail and for the points of dark shadow. Have a go...
 

This sketch was made using Faber Castell Pitt fibre-tip pens - a light grey and a black. It's like a pen and ink wash and is very versatile.
I will post some more like this in the coming days...

This sketch of an alleyway was made with a fibretip pen from a photo. I like the contrast this sort of medium allows. And it copies well.
I stopped the linework short of the underside of the arch to emphasize the darkness of the shadow.

Here are some preparatory sketches I did for an etching. We were in the course of building a treehouse for my brother's children. I somewhat romanticized it...

This pencil rendering of Linton House, of St Peter's in Oxford, was done from a photograph as a gift. I purposely let the drawing be a bit wonky to give it a more character feel. I also spent some time trying to depict the reflections in the windows :-)

 

Once I had discovered that tonal value in a coloured drawing or painting is as important as actual colour (or maybe more so) my work improved no end. Simply put, if you transform the colour picture into black and white, the respective values for shadows and highlights should still be seen clearly - just like in a b&w photo.

Here's the same drawing in black and white :

 

 

I found this old scraper board piece amongst my things whilst clearing out in the loft. It was inspired by ornithologist CF Tunnicliffe's art when I saw a magpie fly by the tree in the garden. https://en.wikipedia.org/wiki/Charles_Tunnicliffe

I did this drawing from a photo as can be seen from the perspective (sloping verticals). It was an exercise in crosshatching using a technical pen. At the top you can see the different layers of hatching crossing at varying angles. This is important so as to achieve even shading. Here's a close-up :

Another sketch London's Soho. Using a dip pen I bought two weeks ago. I love the fact that you can vary the line thickness by varying the pressure. And good strong blacks can be achieved.

Some more sketching in London sitting on the steps of Saint Martin-in-the-Fields. Here I used a Sharpie pen for fine detail.

These self portraits were done from life...
