No, don't hard prune or even 'cut back' - just take out any dead or diseased wood and crossing branches. Dont do it until late June/early July or you'll run the risk of it contracting Silver Leaf Disease.
It certainly looks ok from here and its shape works really well with the foliage around it - but as it's obviously been around a few years it can probably do with some tlc and a good feed like the rest of us, and like the rest of us the bark gets a little craggy as we get older too.
It won't last for ever, but treating it well will keep it going a while longer I'm sure
