That tiller looks good. My first bow wasn't that good. My second would rival that though
for a 30" draw in a regular american flat bow design I would have that bow between 72"-64" around there. The tips could have been thinner but with them being the way they are I would put on a fast flight string. With it being an English longbow and 30# at 30" I would cut it down 2" for every 5# you want it higher. So if I was doing a 45# bow I would cut that 3" off each end. I wouldn't make it any shorter than 72" unless you are not drawing it the full 30" it could get 2" shorter for each inch shorter draw length. Nice looking bow though!
