Last one looks awful. The normal map is so deep/contrasted. Also just because the diffuse is tiger textured, doesnt mean that those are actual veins. Other than that they look blurry, too low res and you need to render with some anisotropic filtering or other better filtering option. The flat angles are super blurry. Basically look at the two bottom leafs of your fern, they look blurred to hell.
The first one looks great. The second is alright, but there's too much lighting information in the diffuse. I'm not sure if you did this intentionally to eliminate a specular map, but generally you want any light/shadows to be handled within engine or with spec/gloss (spec power in UDK).
dpadam450 is right about the third. That normal map is far too intense for grass.
Another thing to consider would be outright removing your normal maps. They significantly increase rendering time and do little on ground cover anyway. Can you even see much of a difference with/without normals in engine?

Thanks for your critique. I have changed the normal map and I worked on the lighting a little bit, but the render is actually a screenshot and not sure how to set the anisotropic filtering, but I will look it up. I do see the blur.

The image is mirrored, I wanted to fill the texture space. Yes, I could have used a different leaf, but I didn't for this project. Thanks!
