It is a great piece of music for your first attempt, I can understand that you miss the sun a lot : ) but now you have a new way to express yourself, btw I would recommend setting the background photo of your PC into a sunny day, I think it can help even if a little bit.
Where I live it is sunny all day long and you can feel the sun rays on your body every day, I sometimes walk to my work (a 30 minute walk) so I get a taste of them, while I am walking, I always wish for a random cloud to cast a shadow on me, and sometimes I get my wish, but sometimes I don't, but the thing is, the sun it is always up there, no matter what I wish for jeje : )
PD: that card challenged is driving me nuts XD I never thought this would be so hard D:
