No, sir, I am not, and any 'planing' I do is down to officially-prescribed medicinal drugs..!

No, seriously, there is already a splendid 'sticky' topic giving bucket-loads of advice on home recording in general; any 'mixing and mastering' tips would, I think, find a natural home there. I'd post tips there myself, but for lack of competence. Disclaimer: I'm an old, half-deaf dummy with limited skills but almost unlimited time to devote (until my Last Trump is sounded, naturally...), and, once I get an idea in my head, I just work it through until I'm satisfied that it won't get any better. My 'mixing' consists of listening, then listening again; repeat ad nauseum until I like it. I use 3db steps when altering levels, as any less makes no difference to my cloth ears. For mastering, I used to cheat by using AAMS, a mastering software suite with a whole lot of presets; I'd just choose the genre I thought best suited. Nowadays, I'm using Ozone, with another set of presets, with which I do the same. Yes, it's lazy, but my competence stretches no further than that.
As for 'subtle': that's the first time I've had that used regarding any of my offerings, and I'll take it as a huge compliment (such is my vanity...). It's far from the usual epithets associated with my contributions. It can't be down to my failing hearing; maybe I'm just getting a little bit luckier..? Many thanks, in any case.
