Since he first crossed my consciousness nearly a decade ago, Mark Joyce's development as a painter has been in a series of curves rather than in a straight line, His early pictures were small, witty, charming, offbeat, and seemed to create an imaginative mini-world of their own; they were, in a word, original.

From there, however, he progressed into greyish, rather indeterminate abstractions which suggested that he was groping tentatively rather than finding. They were not bad pictures as such, since Joyce is a natural-born painter, but they did seem amorphous and rather transitional; it appeared unlikely that he would stop there.

This Green and Red exhibition does not entirely solve the puzzle, though the fuzzy-abstract period at least appears to be well past. The pictures, once again, are small and crisp - rather too small, perhaps, for the Lombard Street gallery, and its little brother in Fitzwilliam Square might have been a better choice. There are not many of them either, and the space does tend to shrink them physically, but a certain quality of presence saves them from being swallowed up. There is some of the early fantasy back again, though not quite the same originality and quirkiness. Neat, painterly, witty, with a sense of emotional detachment, the pictures make no obvious statement beyond being elegantly and presentably themselves. The imagery for the most part is fairly stock - figurative themes mixed with abstract motifs, all sparsely used, in well-chosen but mostly subdued colours and a slightly decorative quality overall. It makes for a thoroughly accomplished exhibition, but again I doubt if Joyce will stop at this point for very long; he still seems to be travelling rather than arriving.

Runs until March 14th.
