You cheat. You haven't changed much. The renders and brushes are still in the same place that Akira placed them. I have checked the PSD file.
(Well, you may of moved the renders slightly but you used most of the ones Akira provided)
Anyway, the thing is a mess (no offense), the renders shouldn't be overlapping the blue area.
Try again and use your own stuff, don't use most of the stuff provided in the PSD file. If it doesn't work, keep practicing, you'll get there eventually. ;)
That's my rant, now:
