To your other pieces,
The introduction, nice drum beat followed by a guitar, I like that it works well for this style of music and sounds good.
At around 00:50 the guitar starts to change and I really think it's a good riff there that you used, sounds realistic.
Back to the drumming now from the start into more tunes, it works well though I'm not entirely sure what's going on.
I like the ending, how it suddenly stops and fades away. Nice work.
Please contact me if you would like to use this in a project. We can discuss the details.
