Check out hickory a little more and you may find that hickory wants to grow straight, also,look up bitternut hickory/bark and see if those background trees in pic 1 match up,bitternut makes good bark on bows that are indestructible,hickory was for me and is for all a great beginners wood.
Those shrubs(buck brush I call it)will make excellent bows,I cant believe how snappy this little sucker is!! There are several different types I've found and have only tested one,I'll try to get u a pic of the bark,RON
