A self portrait should say something about the artist portrayed within it. This shot shows me thinking, something I do a lot of. It is taken in the room I grew up in as a boy, it shows my bookcase, I am a big reader, rendering myself in colour in the first image shows that I try and find the interesting and enjoyable in a too often grey and mundane world. The t-shirt I'm wearing shows that I'm into music, the band in this case being the Fields. The bunk beds show that I am not an only child, I have at least one sibling.
So I guess it depends on what you think the image should show you, and what the sort of image is. I think for a self portrait you can get quite a bit of info from this image.
