Stumpy English Elm Bonsai with multiple trunks getting a good prune

An English Elm stumpy multiple trunk bonsai getting a good prune. Its now June and the main growing season and bonsai need constant attention. This English elm is an unusual tree being stumpy with four main trunks, it does have lovely craggy bark as well. I like it a lot however I don't like that's its a heavy lump!
