First impressions: In the first one you have cropped off the back half of his tail and his body is not in focus. Myself, I prefer to see the whole animal. For the second one, only his head is in focus - maybe that is what you intended - don't know. You need to smaller shutter opening - f11 or f16 maybe. Also, in both images you have placed the animal, or most of it, almost dead-centre. This placement does not usually yield a pleasing image. You might want to search the web for the "rule of thirds in photography". This is an established guideline for the placement of objects - head, eyes, etc. in an image. HTH.
