If the parallel lines in this shot are supposed to be in the floor, you should probably compose and expose this shot for that. In this case, the focus and title of the image is the cat, and although pretty, doesn't have anything to do with the challenge topic. The floor is out of focus and slightly overexposed where the sun hits it. The cat even appears to be slightly out of focus.
While the concept is there (parallel floorboards and the lines on cat's bow(?)), the picture itself is somewhat unexciting and not too creative. It's also a little fuzzy and the cat's position is a bit awkward. Great-looking cat though, and I like the lighting in general!
Too much direct light on one side of the cat and not the other. The main section of the photo is shadowed and the floor is overexposed from the sunlight. Perhaps taking several steps further back would have given more of the wood floor and had the cat highlighted in it's patch of sunlight.
The floor has parallel lines, so i guess you meet the challenge, although the fact that the floor has parallel lines does NOT make this a stronger image; it's just a coincidence. The subject itself (the cat) is poorly lit.
