i'm not the greatest at seeing auras in photographs so i'm sorry i can't be of much help. from what i could see it's a few inches away from your body, and while i've never really been able to see colour, i didn't really sense anything negative in the picture. why do you ask?
work on seeing your own aura, meditate first, then place your hand a few inches away from a wall of a solid colour [i prefer dark coloured walls, but most use light colours] try to look past your hand [i tend to unfocus my eyes slightly] soon, you should begin to see a glow around your hands a few inches away and as you continue, you should see colours start to emerge. granted, if you unfocused your eyes too much, or they start to get soar, you're probably just seeing your hand just unfocused. so be sure to rest your eyes often. try seeing others aura's throughout the day for extra practice. i find it's easiest to see auras around a persons shoulders or top of their head.
