Nice work. Your banner style one seems to me using a different typeface to the other 2 (Sabon?)
I agree, the colours are fine left as they are. The only thing that is making me unsettled is that the right hand 1 in "11" is a tiny bit too far to the right, which makes the space between the 2 digits a tad large, but also off-centre. If it came to the middle a tiny bit, you'd have an even space between the serif at the foot and the circle. I'm being REALLY picky cos it's so close to being bang on.
I also wonder if there is a typeface that would echo the hand tooled nature of your whittling? Can't think of an easy answer to that last question though.
