What are you using to take screenshots? This picture looks quite squished.. Have you tried pressing the Print Screen button on your keyboard and pasting the picture into MSPaint?
Also, I think Ratty means that this town looks pretty bare. Even if this is just a field or garden, it's a little bit bland. In real life, when we see vast spaces full of grass we think it looks nice like a tidy park or something. In video games, it's unfortunately a different story.. Take a look at this tutorial. It shows you how smaller spaces filled with more things are better than wiiiide open spaces with nothing in. You should use large maps sparingly unless you know how to fill them in an interesting way. I hope to see you learn and improve your maps!
