Hi Al! This sounds great! Powerful and punchy mix, well balanced.
Being super-picky, I think maybe the lead vocal could use just a tad more "air" on it. The toms sound superb on your mix, but I think maybe some of the tom hits later in the song a just slightly louder and pop out a bit too much.
Overall, top job!
Oh, and thank you so much for your support in buying the album - I hope you have fun mixing the songs!
