justin! - me again! that really is a nice bow!
it's always so hard to judge the tiller from these pics: when you pull it, i'd call it PERFECT, when your nephew pulls it, it looks like a bit more bend mid-limb on the upper limb wouldn't hurt. it's probably just the way it's angled. or did you work on it some more after the pic of your nephew was taken!
the wood combo on the riser looks phantastic; very tasty!!
this for sure is one of them bows one can learn a lot just by looking at it!
thanks, frank
