natural imperfections

So I got really good feed back on my 8ft tall collage today in my art class. They had some interesting ideas about it too, repenting, doing bad things. They thought it was even more interesting that I made it as "stream of conscience" piece and had very little prescript plans. The teacher even wanted to talk to me about it after class. That was pretty cool. When he told me he wanted to talk to me after class I thought my collage could be considered offensive. I don't know why I thought that since we are in collage and everyone in that class is pretty mature. Maybe I should do more 8ft tall collages. My teacher said I take the imprefections that the collage and cardboard has to offer and I embrace them instead of trying to hide them. Which is definitly true about my art because thats how I like to make art, with its natural imperfections. Kind of like the noise music Im making now.
