You asked for a feedback on reddit, but I'm not able to comment with an image there, so here it is:
I like the style, especially the pastel colors!
I think the main thing to worry about are the shadows, try to unify their direction.
For example the house has only shadow on the front but there is no shadow around the house (the corner or left and right side)
This makes the house look like a paper cutout without any depth.
try to add something like in position II.
Your way of doing shadow works with characters but not with bigger structures, especially when you added that white curb for the house.
You did good with trees.
Also try to unify the way you use black outline, in position I. i colored the previously black line in dark brown like you did with chest and trees, i left the outline black because i presume the house should be interactable. (characters and interactable objects usually have black outline)
The same principle is basically in position IV. with the tree. but that one i leave to you, it is an artistic choice and i see your prespective is more of side view than top view, so it works here in my opinion.
BUt for more top-down view the tree shading should be done a bit different.
I think you should get rid of some colors that do not add too much to the objects. Like the greeen tree in position V. and Grass in position III.
The tree uses two very similiar green colors for its shading, so there is no point of using two colors, pick one or use darker/lighter color.
Also same thing with the grass and path, the shadow on the path was very light (you either want to add shadow or you don't, so go bold with it.
Anyway, really great work overall, and I wish you lots of success with the pack!
