I want to find a job in a small studio (outsource) or a small space project.

And you would like some advice for your job search? (Because that's the purpose of this board -- advice, not Help Wanted or Job Wanted ads.) If you have a question to ask, this is the place to do it. If you want to advertise your availability, please use the Classifieds. Thanks.

I have appointed an adequate price for a art or not? Because it is my first attempt to enter in a worldwide gamedev and I don't really know prices and subtleties,

That's not a question for this board. Someone who has a "job" (the topic here) gets paid hourly, not by the piece. Freelancer pricing is most likely a Business topic, or maybe a Visual Arts topic since you're talking about freelancing as an artist.
