Gilljc, I'm a very long way from being an expert, but I think Chippygeoff's quite right, it's purely a matter of personal taste. If it were me I'd be very pleased with the look of both your "K" and of the whole piece.
But re different fonts, do you have MS Word (or some similar word processor) on your PC? If so you'll have a load of fonts already included. If not, or if you've already checked your Word and don't like the fonts already loaded, then Google for free fonts - there are several web sites that allow you to download fonts.
Personally, with the little I've done so far I just fiddle about in Word until I find something that looks OK to me, print it out at about the same size the finished wooden item will be, then show the paper to my wife. If she says "OK", then I'm in business!
