Posting a picture of abs to twitter/facebook?

[Go Fish]

Just now I was planning on posting a picture (profile picture) of me topless to twitter . Now I was gonna use this as an experiment to see if I would gain more followers quicker (not a follower seeker, was just experimenting). This is the picture (one's edited, the other isn't):

As you can see, facial-wise I haven't got much going for me, but I do have natural (don't hate, I do a bit of athletics too) abs. So, would I look like a d-bag if I did put this as my profile picture. What would you think if you saw this? I'm not actually full of myself and I keep myself very open but also quite modest (however, I do jokingly be cocky sometimes). People from my school follow me and I'm a bit afraid they might judge me for it? Would you? Btw I'm 14 approaching 15. Thanks for answers
