I went and submitted an entry on my LiveJournal about reflections. I'm thinking about a few ways to illustrate a few common concepts and scenarios, and would like some input. While the post is here, if you would rather comment on anything here on my dA journal feel free to do so. You'll get a lot of poorly-drawn stick figures for most of this exercise out of me, and some photographs.

Also. I am willing to help revise and assist with sketches if you're doing a reflection scene, from either doing some stick-figure ray traces to just saying things like "hey, we should be able to see the underside of that bridge in the river, not the top"
