English is a little problematic. But man, that's ok, it's your choice, at least what's important is the download link is available. But it's best that you put a warning label that it'll take some time to load if you still don't want to insert a preloader, which honestly it's very easy to create if you find the right tutorials. Imagine a future project of yours that could end up 5MB+, now that definitely need a preloader.
All in all, don't rush yourself. Take your time till it's polished nicely.
