Illustration itself already “speaks for itself”! I will suggest you read pictures first without reading the actual words in the book, and ask your readers what do they think about what are those pictures telling them? Then, you can decide wether or not you want to read the actual story afterwards.
“Like the gardener, thankful for every green sprout, and the fireman, for putting the fire out, there are everyday blessings, you din;t beed to look far, to know at a glance, how special you are”
count daily blessings, think about what they can thanks for on daily basis.
Everything could be blessing for someone, anything could be the thing to thankful!
