The tutorial looks very fine, if it was better visualy planned, it would be perfect.
but...
The site itself looks like crap.
I suggest:
Music: from
here -> 70 different MIDI's, you will surely find something good for you there.
Background: more or less fine, but not seamless. Maybe you can recolor something from
here.
Music is just collected by me and sorted\rated. Textures are entirely made by me.
(edit):
I understand your patriotism about that music, but there is TONS of better versions, not hurting my ears.
