Congrats! Remember that it's just the beginning though, continue preparing your brand for being revealed to the public. It doesn't have to be too overwhelming, take care of the essentials: decide on your artist name, secure social media handles and a domain name (which can redirect to a social media profile of yours at first), arrange either graphics or photos for your socials (or both), start posting regularly on a few platforms you like the most, e.g. Instagram and Facebook. Start building your presence online even before your music is available publicly.
Speaking of the music, I would recommend getting early feedback on your demos, and Audiokite, now a part of ReverbNation, is a great place to do that. When ordering a report for a song, specify it's a demo, so the listeners don't judge the production quality. US-based music listeners will provide feedback to your song, or songs, which may be very helpful at this stage of your career. You can try Fluence, as well, as there is a lot of music critics and producers who will provide feedback to your recordings for an affordable fee.
If you don't have any existing contacts in the industry, I recommend self-releasing your first single, or the whole album or EP. The label you may find now may not be much help, and more influential labels will almost certainly not be accessible yet, no matter how good the music is, unfortunately.
