Thank you!
For most things I drew them with circles and lines, the plants are made up with an array of points (Number of points varies with a random range). With each point the fake z position of each stored point increases linearly and more slowly the points x and y positions extend further out in a random direction determined when it is created. Then I just drew a couple leaf sprites and had them drawn at the last point. Then I loop through the array and draw a line at each point, the fake 3d coordinates are calculated almost exactly the same as sprite stacking.
Hope this helps!
