Since I replied I failed another 8 or 9 times. But the day will come when I got the trick! xD (btw. its step 2 I'm talking about all the time LOL^^) Maybe it's just my eye that isn't satisfied with the curves! I'll try even harder. When I ever get a result I'll link back to you.
I would suggest that, even if you dont like how it looks, finish it anyway. And then start over and finish that one. Do like that until you find what you're "doing wrong" and start over again. You wont learn as much if you quit
