Where I live, we assume that "more adjective practice" is the only spelling that makes sense. "Practise more!" would make a good imperative in British English, and in some regions, e.g. Australia, "bloody" can be inserted anywhere, e.g. "kangabloodyroo".

Depicting strings (of musical instruments) in oil paintings can be a problem. Some painters used to scratch them with a knife, so that the bare white canvas shows through. But then, which self-respecting painter would paint an autoharp?
