very nice bow,and from an oak board to boot WOW
i have came back to look at this several times before i decided to post,just couldnt think straight about it after first seeing it,incredible curves.
i have seen a couple of others i thought would make great BOM candidates,however this could be the winner right here.
very nice,tiller looks dead on,love the design.
i would leave it just like that,no paint.the grain orientation makes like you said great natural camo.
peace,
tim
