Being your first, it was probably bad, but probably not as bad as you think it was. The thing is, most people forget everything they saw in a talk by the time the next one is finished. They might, however, remember your face, name or topic, and that's the best you can hope for. Next time you submit a funding application, you hope that one of the reviewers has heard of you. The more talks you give, the more likely it is. You'll get better at it.
