No worries mate you're more than welcome.
Ben has covered pretty much the second images main faults and these are all in the way the picture was originally captured - try and not use the oncamera flash unless totally necessary and if you do have to use it something like tissue paper over the front of it can help to diffuse the light some what (not ideal but definitely better than nothing).
The result of using the on camera flash has caused some heavy shadows that are pretty much impossible to recover from, this also gives a really harsh look to the image when you were probably going for quite a soft and sweet look for such an adorable youngster.
If light is low rather than popping the flash look around for alternative areas and shot ideas a window or open doorway for example and then use the natural light to dictate where you position your "model".
Not great by any means but I have had a go at editing your image just breifly and have put it below, the basic steps were:
1: A slight crop off the right hand side
2: Adjusted the curves
3: Shadow Highlight to try and soften the highlight on the cheek and upper lip a bit
4: I worked on the eyes a little with some dodge work
5: I lowered the exposure level ever so slightly again to try and lower the highlights as I was hoping to recover a little more here but can't get it any better.
6: Cloned out part of the door structure on the extreme left as that was distracting
7: Unsharp Mask
8: Colour balance adjustment
9: Hue saturation adjustment
10: A very soft Sepia filter over the top
11: Save for Web
As I say it's not 100% but I think it's a bit of an improvement, you have a gorgeous model there and that's as good an excuse as any to keep practicing!
play around with light and learn what works and what doesnt, read as much about lighting as you can spare the time for. It's all a great way to improve your shots.
Edit to add: I have just gone back in and cloned out the two awkward catch lights above and below the pupil on the eye that's right of frame.
