oh damn 3w of fever, it must be a hard time... I have taken some medicine and I feel a lot better now. I'm happy that new mappers like u try to find others for modding! It means that u have that passion at mapping and want to improve, I'm always welcome for u to come and find me about modding ur next map! Anyways gl and hf on mapping.
It's okay for new mappers that come into rhythm issues, I used to have serious rhythm issue as well! In this case I will suggest u to map more different songs first, then go back and remap/mod this one, when u have the experience by mapping more u will be able to find out issue by urself quickly and more precisely.
