Custom Illustration/Graphics

We are redesigning our homepage, and need to improve upon 3 specific graphics that visualize our website's process. The website is a mobile video sharing community (will provide more details when we get started). Attached are the 3 graphics that need to be improved upon. First graphic: Is trying to show that there are so many different kinds of groups that someone could create for our site. Want someone to see this graphic in tandem with the text (to the left of it) and immediately have a reason to create a group to share mobile videos. Second graphic: Currently this graphic just shows a mockup of an iPhone with the content submission process. This is fine staying the same unless you have a better idea! Third graphic: This one definitely needs to be redone. We're trying to show that after people post their video, their friends can easily watch it on their smartphone or computer. If this project goes well, there's a definite opportunity for immediate, additional work. Thanks for your interest!
