Votre anglais est bien, Alphaelis. Je crois il ne sera pas difficile.
Beaucoup de producteurs Japonais, Coreén, Chinois et Espagnol essaient de faire des chansons anglais.
Parfois, il ya des un grand nombre des erreurs et la musique est très bonne.
C'est votre choix.
(Sorry about that. I'm trying to re-learn French since I've been out of school and forgot most of what I was taught. So I had to check how much I could remember.)
As for Leon, I think it's good that you got him, Ant. He'll probably be good practise for later releases as well as a Vocaloid that needs more original songs made with him anyway. Adjusting the parameters could probably fix some of the problems but there might be some differences I don't know about since I've never messed with them in anything pre V3.
