I watched the video and those are some pretty cool graphics, I never had the talent nor effort for doing graphics. You're talented and I know you can grow big. Btw. check out utopian.io a site for programmers of open source projects, there are a lot of Task Request, where a developer wants a cool logo/graphic design for their application. You can also make suggestions there, without a request with your logo to a project. Then if the mods accept your contribution you'll get upvoted by the utopian bot, and other people!
