grass poking out of rocks

You have got a situation of contrasting shape and texture here which is the basis for an interesting shot, but you have not made the most of it. Composition wise you have not made good use of the material, putting the plant dead centre and looking straight down. Also there is complete absence of any directional light which would have emphasised shapes and cast shadows.

You've probably heard this before, but good photos require good light. Here you could make your own with an off camera flash or flood, or you could wait till the end of the day and catch a strong directional low sunlight on your scene.
