Perhaps some advice for the future?

[TheMausoleumHorde]

Hey guys my band just launched out first demo and we had done everything ourselves in my home studio and was hoping you guys could give us some advice for perhaps future recordings and for promotions? Keep in mind its pretty raw and there are a few glaring mistakes but the energy and songs speak for themselves IMHO.
Let us know what you think! we play Black Metal
