May I try fiverr?

I already have an account, and one gig, not very worth it, but I have'nt done more because I don't have images of my work.

So, what I was thinking was to get some things done for a week or two to show to the world, but, do you guys think it is worht it to try mainly on fiverr? I've tried swagbucks, and other sites but havent got nothing over a few weeks.

I know a lot of things like drawing, languages and writing, so perhaps I can make it, or no?
