First off, awesome! But why not ask your tax advisor? If you don't have one you definitely need one anyway. Per default you're presumably still a tax resident of Denmark but depending on where you travel and how long you stay there you might owe some taxes there too, assuming you're officially even allowed to work there. I'm not sure how much e.g. an offshore LLC would improve that situation given that the LLC then still needs to pay you personally, but a professional tax advisor should be able to tell you more.
