It's a WIP of the hometown, so chill your nips, hahaha. :3
You're posting work here for criticism so you can get better, that is the point of this forum.
Since that a WIP of the hometown you should take my criticism into consideration. What I don't like could be what other people don't like.
Mine <---> Yours
If you show us the pixel art before it's in flash under all those NPA effects it'll be easier for us to show edits and generally help.
Most of the edit were on the house and the immediately surrounding area. Palette too!
Placed the new barred windows at the first floor height. In your house there aren't any windows on the first floor. Though if there's only one floor then nobody can look through them, just thought it was a better placement.
You've got a chimney. Let's use it.
Added some simple grass. An ugly rock too.
Threw some edge highlights on ... the edges...
Rocks and mountains and most things in nature that are viewed as grey are more often than not several (usually dull and muted) colors. Besides, adding a little color will help convey moods better. My rocks have a little green, orange or red in them. Makes it a little warmer. If you want to go cold try some blues or purples.
Threw in a ladder and birds for good measure.
