Newbie in digital art!

I know it's been a while since my last post and hopefully this will be the beginning of a daily rutine.
Although on extended vacations, I've been quite busy with french classes, driving classes and now with a mural painting due for the end of the month, but excuses are just...well excuses. Clean state and all, I started this painting a while ago and just now finished, I'm a newbie in digital arts so went over a couple (hundreds) of tutorials and online magazines to learn a trick or two... Practice makes perfect, right?
I was having trouble with the background and I painted it over too many times, finally I just went for a brush.
