Not a bad first effort - in fact you can get a kit of 4 close up filters for your lens which would help you get closer for very little money:

They screw on the front of your lens and can give quite good results - but make sure you get the right filter size.
They are not the same as using a genuine macro lens but for vy little moy will start you off although the +10 is so strong that focussing is a real problem.
In fact that is the main problem with your photo, you have missed the focus on the eyes which is probably why you described it as not getting the clarity.
Macro photography is extremely difficult at first and if you are using auto focus you are probably better turning it off and focussing by moving back and forth to get the focus.
But you will still get a lot to bin - we all do!
But keep at it and you will find it very rewarding.
It also helps to practice indoors with a tripod and small flowers etc - I used to go out with a pair of clippers and a small plastic container to collect small flowers, daisies, dandelions, buttercups etc and photograph them indoors - so much easier with no wind!
