I just discovered today this great artist. I love her style and she even has a few Valentine related stuff. Well if you're into Team Fortress 2 that is. Be sure to check her out.
Strangely enough, that was the second love-related TF2 reference I saw today. The first was from the well-known British game critic, Yahtzee. At the end of his latest review video he included a very touching love story.

That's all from me. Have a happy Valentine's day if you will.
