I've followed closely this series of arts you have done, showing these feelings. The art is simple, yet good, and its simplicity is what attracts me. Love the background color, the character shape, and the effects that describe each feeling, it all fits in perfectly. All I can say is keep up this fantastic work. While not all of us post comments, at least rest assured that it's something I have used for avatars (MSN, AIM, cellphone background, forums), and people have asked me who has done it. Personal favourite is Bursting Heart.
So yeah, this is fantastic, and if you can do more like these, it will be fantastic
