The work was hard as I had to learn how to make studio quality recording using only my cheap equipment, but after many long days placing microphones and tweaking gain knobs I had good results and I could start recording.
I didn't write any midi track or score, I preferred to play directly on the movie and record all my instruments with my stompbox effects set as in the final result, the mixing itself was mostly about volumes and a little EQ without much manipulation.
It was an occasion to learn properly how to play guitar, but I didn't felt the same for the drums, so I recorded every single drum singularly (I also didn't had that many microphones/inputs)
As an opensource software love I was impressed by Ardour managing around 100 tracks for the lenght of 10 minutes of movie on a computer held together by dutch tape.
