Great start. Overall I like this map a lot, but there are a few things that can make it better.
1: Stop calling a 10ft x 7ft pool of water a "lake". OK, that was a cheap shot, but I couldn't resist. The 2 problems are that it is to bright a blue color, and a pool that size would only have whitecaps if there were an earthquake. Try a water texture with ripples in a darker color.
Here is a nice little pond and some water pieces that might work better
2: The trees look great, but you can create more illusion of height by using a bit more shadow under them.
3: The flowers are probably to big. At the current scale each flower is about 14-16 inches across.
Now that is all just my opinion, but a few changes could make a good map into a great map.
