After spending some time contemplating this alongside previous self portraits, I come to no conclusion. Certainly there is predilection for the arras, albeit mitigated by seductive transparency, but on the whole I fear me should a certain Great Dane visit your house. I mean you have shown where is your heart.
aaah...there is. I've looked at this image 4 or 5 times because I knew there was something I should be seeing. I've never tried a shot like this but the general rule of thumb is to have the person in front of the camera for half the exposure. (i.e if its a 4 second exposure the person needs to be in the scene for 2 seconds). tough to manage on a self-portrait but I think you weren't in the scene long enough and as such the image of you in the scene is very faint.
