Thanks, haha, I thought bathroom tile idea was a bit different when I thought about it too lol. I just used ordinary pencil, and smudged the dark part on the outside with my fingers. I did try to make it look a bit square-like, rather than having many curvy edges in it. If that made sense..lol. Another thing I'm in the middle of drawing at the moment is a bit like the bathroom tile idea. I woke up one day, and the light was reflecting on one of my band posters on my wall, and in my head I could see an image on the poster from where the light was reflecting [other than the band that was on it]. I could see what looked like a giant face that only had a mouth, a weird face that looked a bit to me like that little puppet off the film 'SAW', and then two little people that looked to me like the were watching the opera or something . I guess you could say it was just my imagination running wild, but either way it gave me the idea to draw it, haha. I might upload it if it turns out good ^.^

Thanks again
