When it comes to reflections you must keep one major goal in-mind, that is you want your viewers to look at what you are trying to get across to them. In this picture you will see the reflection of what seems to be another type of vehicle with the tree's in the background(and that's fine) but what you could do is attract the eye with something that represents your BMW and what it means to you as a person. My (opinion alone) I would place a small table in front of the hood while it's up and place a quare mirror (about the size of a dinner plate or tray) on the table, then putting a wine glass with something in it:>) and maybe a red rose along with a small candle to accent your love for your BMW. Once the table is set-up take the picture when the sun is just about to vanish from the horizon. I will promise you that if you take the picture from the right angle, it will eventually be framed.
