Agree with Run&Coke's comments. When photographing animals it's important to get the point of focus on the eyes. I would also say that the DOF (Depth of Field) is a bit too much and I find the plant is a little distracting. Try increasing your aperture (smaller 'f' number, such as f4) to blur the background a bit more.
Apart from these things it's a nice photo. Keep practising
