Yeah, the scouting aspect can be viewed as a proving grounds for the artist. It also helps to deter people from making alt accounts and flooding the Art Portal with garbage for whatever petty reason might to mind. The ones who scout also have to be careful, because if the people they scout start breaking rules or their art is not of a quality that genuinely reflects the creator's effort and desire to improve and express him/herself, then the scouter can lose his status, along with the person he scouted.
One way to be seen, despite being unscouted, is to participate in contests or holidays. The rules will typically request that you tag your art (like "Halloween2017" for example) and, if nothing else, the judges will see it. If one or more of them like what they see, you might go from being unscouted to frontpaged (along with being scouted, of course).
Your drawings remind me of when I would try to draw all the pictures I saw in my issues of Nintendo Power an within game instruction manuals back when I was your age.

Yeah, it took me a bit to find out about the scouting system. Read the rules of scouting, and I can tell you from experience that scouting someone new can be really nerve racking for the scouter (or that's just me). Anyway, remember to always try your best when posting art!
