Visiting now. I'll give some feedback as I go around

It looks like you have a lot of hybrids and regular flowers around town which will be really useful for landscaping. Your house is in a good spot. If you want, maybe use a line of trees/bushes behind your house by the river bend to make the peninsula your personal yard/garden area!
Maybe plant some cedars and shrubs around your campsite to make it somewhat separate from the town plaza.
Speaking of the plaza, it's nice that it's by the town hall. You could make that area a big park.
The little bench you have in front of the pond by Re-Tail is cute. You could make that area along the river another park/greenery area.
The strip of land between the south river and the south beach would be great for a long path with some benches. The river looks like it winds around a lot but you could really work with it and make it look great and utilize all the little nooks you have. The cafe could go north of your bridge and you could make a plaza in front of that, for example.
Let me know if you need help!
