The "crinkled" look is what a lot of us like. Antique quilts all look like this because the cotton batting shrank when the quilt was washed. If you do not want this look, you need to use a polyester batting (does not shrink at all). Hobbs Polydown is a nice one.
I would think that more quilting lines would result in a less-wrinkled look. Try another sample with closer quilting. (If it is a lot closer, you may want to switch to a finer weight thread to avoid adding stiffness.)
