I'm pretty skeptical about this demo.
Good things about it are:
- very clean and clear sound for an old tape ripped in low bitrate
- interesting music with good technical and atmospheric parts
- awesome cover artwork
- loud bass which is a big plus, I like loud bass in my Black Metal
- nice melodies
- vocals that are a bit annoying but fit the music well
- very good acoustic guitar parts which make the demo feel progressive and interesting
- good symphonic keyboard parts which follow the music and make it complete
Bad things:
- Too much vocal presence, I'd prefer it to be more instrumental
- bad drum machine, it's too loud in the mix and distracting, ruining the overall enjoyment of the music on demo. If it wasn't for these annoying drums, I'd really like this demo a lot more.
- guitar riffs borrowed from melodic death metal (in some parts, not all the time) which I really don't like.
- didn't enjoy the clean vocals but there's not much of that so it's okay I guess, I can tolerate even if I don't like

Best song on the demo is
Secrets And Tales Of A Blackened Sky, I like how epic it feels, good riffs and tempo, it's very powerful. I wish entire demo was more like this song.
