And what exactly would you like to improve? :D It's perfect.
The lighting, blurred background, framing, details.. Picture is sharp and professional. I love the composition, it's great.
After all these technical things, I must say that the thing I like the most is the look in its beautiful eyes... A bit sad, but still - wonderful.
Please, do continue with your fabulous work, I'm really impressed with this one. It deserves all the praise and my favourites. ;) Thanks for sharing it!
