Learning photoshop: This time I drew my friend

So here's my latest work! I asked a friend of mine whether she would like me to make a portrait of her, and she was all up for it. It wasn't possible for us to do it live at that moment, so i decided to take a photo of hers as a reference.
Did this in 4 hours (can't believe it! My last one had taken me 4 days! But that was much more detailed as well) sitting from 12 am to 4:30 am (almost on a deadline, as I had to move my PC the very next day) 
Personally im very happy with the results, and im hoping i can keep up this momentum of drawing regularly. The shorts didn't come out that good though, as I began to lose a little bit of patience at the end. :P   But im pretty happy with the shirt.
 
No background yet, might add that in later

Oh, and needless to say, my lady friend was impressed.
Mission accomplished ;)
