In any case it is the wrong time of year to prune back that kind of willow. The ones which produce catkins (as your twisted one ought) should be pruned back after the catkins have finished. They come on new growth, so you remove the old to encourage new and thus get more catkins. Mind you at 3 feet high, yours still has a way to grow and can be left alone, except for removing any dead branches once it has got leaves so you can see which branches are alive.
