Well, this was totally unexpected, and AWESOME!
It seems like you really took to heart the critique for the last song, because this one is in a whole different direction, and it's clear now that you are quite talented
Some things to consider (mind you, I don't compose music myself, so this is a layman's opinion):
• In the song, I feel like some of the balance between instruments could be tweaked and improved. The bass is kind of tinny to me, (which might be intentional, I don't know), but tinny base like that doesn't fully complement the strings. Since you have strings in there, I wonder if more orchestral-oriented percussion would be more suited (the actual base line is fine though).
• The song sounds a bit rough overall, I'm not sure if this is because of the encoding, or just a quick mixing job. The different instruments jumble together a little at times. Also, I think the guitar is over-distorted.
• The little touches, like the keyboard riff, etc, are cool
That's about it, really. It's definitely great. Hopefully we will hear some more music from you in the future

. I think it would be a great thing if we start to see music that goes beyond synths and techno/electro, where artists try out more varied instruments, different moods, and interesting melodies. This is surely the start
Oh, and some notes-
Something James Bond-y about this one
