It was made clear at the very start of this Challenge, that the criteria of recording quality, production, technical ability and more were (and, for me, still are...) essentially secondary to the inspirational and composition elements of the work proposed. Not everyone has a studio at their disposal, nor even the domestic conditions for professional-level recordings, so the pieces with background noise, some 'flubs', a low, or too high, level can still be appreciated for the idea behind them. Some may benefit from a heavenly choir, others a soft trumpet solo or a Trinidad steel band, but, even without any window dressing, a Good Composition is a Good Composition. I would humbly offer some of my own renderings as model of just how little technique is required; some of my pieces have even been voted as 'best', proving that it's not always the most 'pro' efforts that are recompensed.
In short : don't sweat it; it's fine as it is..!
