I'm not really into goth stuff, but you really nailed it with this melody... beautiful.. repetitive as fuck, but beautiful.
Reminds me of romanticism, beautiful.. I think you can make a make a gorgeous piece out of this single melody.. You'd get something like Chopin's opuses, of course, just with proper harmony work and good taste ;)
Congrats! 3,5 cus I take this as a prototype of somethin that could be a thousand times better
Please contact me if you would like to use this in a project. We can discuss the details.
