Three examples of alliteration are the word "market-man", the expression, "people the impassive" and the explanation of "not afraid to leave you yet I love you" . This alliteration reminds me of a poem I wrote myself of the plague of the bugs in the Canadian north woods, ie it started, "The buzz of bees and other bothersome bugs in the Babine Bush, Coupled with the whine of the worst winged wielders of wanton warfare..." etc.
instead of using the word roam try to use the word venture. like he had the urge to venture.
hope this helps!
