Of course you can, but as everyone else have already said, it's just more difficult to get people to give your game a chance. But then again, one of the most popular and most successful among commercial RPG maker games is a game called "To The Moon". And while I think it might be using a few edits and such (can't remember) it's mainly RTP (from the older RPGmaker XP). Crazy huh? Well, not really. It's not praised for it's somewhat lackluster (but I guess okey:ish) graphics. It's praised for it's story and the music. The map you got going there looks fine to me (although I wouldn't recommend spending a whole week on a single map). Remember that the most important thing is to actually finish the game. If you never finish, "good" or "bad" doesn't matter. Everything will take more time in the beginning while you're still learning, of course. But if this is your first game I'd recommend that you'll try to make something small and focused, especially if you're spending more than a week on a single village map (that does not seem to be overly complex either). I know because I used to do the same thing myself. I knew I could make close to perfect parallax maps if I just kept polishing and revising them, and so I did. I probably got a few of those maps lying around somewhere on my hard drive still. What I don't have are the finished games they were supposed to be used in - because they don't exist.
