Thanks for all of the feedback guys and for taking the time to listen to it.

Rayc - it was mainly the intentional artifacts (the last word of each verse and chorus) which were meant to have the "autotune-style" sound. As well as the delay and distortion I put on the same words. I liked it but I wasn't 100% sure if it was a bit much. The consensus seems to be that the effects were OK though, which I'm glad about!

I'm slowly getting the hang of the pitch correction stuff. I hope I can get to a point where I'd feel comfortable using it in a song in which I would want it to sound like I hadn't used any correction at all. Fingers crossed all of the practice will pay off!
