Photoshop adventures!

So I'm trying to take my Photoshop to the next level (above basics) and since I have an awesome teacher at my disposal I've decided to do one task everyday set to me. Since my teacher is quite strict and unsparing not very easy tasks are set. My first one was a day to night conversion, something I didn't know was possible in Photoshop!

Here it is. Judge away! Frankly I'm quite happy with it :D






Agree it could do with a bit more tweaking which I'll get to after I'm done with brimming with pride!
