I get to practice my German every day in Germany but I'm not too happy with my accent. I need to work on it.
Can I say, 'My German accent could use a bit of work'? Can you think of a more natural way to say it?
I may have used "a bit" on occasion, but certainly not often. I don't think it is very commonly used in the USA, however I doubt anyone would raise their eyebrows if they heard it here.
