Working on lens flare

I was wondering how to achieve the same beautiful effect you get thanks the VideoCopilot plugin Optical Flare, without having to actually buy that..
searching on Vimeo I found this very nice tutorial that explains exactly that.

This is what I managed to achieve, tweaking a little bit..

So.. hope you like and, especially, hope to be soon able to upload the whole video.
I'm afraid, anyway, that it will take some time.. still have to record all the sound FX and there is still no music at all..
