With his landscapes McNally takes a particular view and stylises it to meet his own impressions. Well known vistas are thus transformed into something which the viewer beholds and warms to, but which would not necessarily bear comparison with a photographic image. Such is the influence of his art that it can tease and sublimely satisfy at one and the same time.

The buildings McNally paints have a solidity and a three dimensional quality to them which gives the impression of a living being. In all that he paints light plays a fundemental role as does the consequential shadow.
