Mine is a drawing I did for this weekly drawing thing I was running for a bit. The prompt for that week was to pick a song and draw the way it makes you feel or just something related to the song. My drawing was for the song Innocent by Taylor Swift. I liked the loving and supporting feel of the song and wanted to draw something that represented that. If you can't read the text, it says: "Lost your balance on a tightrope... it's never too late to get it back."
As for why I decided to make it my profile pic, I'm not really sure. I kinda just wanted to show off one of my drawings even if they're not that good, because I like looking at them and I also really like the message of this one. This one was the one that looked best with the format. Plus, I also think the colors go really well with the Project M forum style, especially with the text color I picked to go with it.
Also, looking at it from the default forum style, it looks like she's pulling you from a world of grey into a world of color into my text colors. That's so cool. xD
