Do not use any stock materials, vector artwork, or ANYTHING unoriginal. It must all be your own work!
See the black and white image below. I want to use a similar style, but to change things in it to reflect triathlons and my brand. We want three sections like this.
TOP: this needs to be altered to have a people in a swim race. replace trees with waves, some on a kayak paddling in from of the swimmers. have a horizon with the sun coming up. etc
MIDDLE: Is the cycle section... Keep the heart section, and have the heart the same as my heart logo.. replace the birds with items that go with cycling. Either side of the heart need to have people on bikes racing.
BOTTOM: the bottom one is running... you can keep everything similar look and feel but replace the bikers with runners.
