Hello :) Here si my entry for your contest. I've tried to create a sketchy/organic feeling, but also reference old reference book illustrations (to reflect wisdom / purity of "tried & true" practice) The color puts the focus on the eggs, but the subtle coloring shows that there's much detail in the creation of the nest, i.e. - there's work / knowledge put into creating a healthy habitat for the growth of life.
This option could be used as a simple, single color logo for stationery / envelopes / tags. It could also be made into a stamp? Just a thought for extending your brand :)
