If I were looking at this bow, with out you asking for comments, Id say it looks great. You did a good job. But since you asked, the only thing I can see (and this is being nit picky)is; If anything, the midlimb on the upper limb is a tad stiff. Not much, just looks like it is causeing you to have an extra 1/8" positive tiller at the tips. But for a kids bow, that doesnt matter one bit. I would not change it if it were me. Especially if I were close to my target weight. Looks good.
