Well, the creativity is there, and that is good.
However, I do have things that I don't like.
- You've used far too many NPCs.
I think that NPCs are good and all, but too many makes a level cluttered. You have a random opened chest in the middle of the grass!
- Your beach is too straight.
You've started with making it more random and more realistic, but not yet
- While I'm not going to edit the image to point them out, you have several tile errors.
Examples include: The cliffs in the top-right, the grass>water area in the top right... The are more, of course.
Generally things could just be a whole lot more realistically shaped, something which I have trouble with, and using less NPCs, and not placing blocking and useless objects all over the grass.
