There we go! The final grey watercolour wash added to the Tower. Now it looks like flint - and when the masking fluid is removed there will be some lighter areas to really enhance that flinty appearance.
Masking fluid removal and next stages will be done in art summer school today - the last one of the summer - boo hoo! Perhaps the weather will improve now summer school comes to an end - and I can take my new sketching toy outside and play ! We live in hope, eh?
