A much better photo would be best when it comes to a main pic. One that's a close-up and with a SMILE, as the one you have now is simply just too serious and you look downright grumpy.
Few women when seeing the main pic you have now, will want to click on your profile. Lose it ( main pic ) as I don't think it's conducive to your selling yourself.
This:
I don't bite, well not hard anyway!!!
God, if I had a dollar for each time I read that on profiles! Lose that phrase, too... it's so over done and terribly cliche!
Your profile states you're looking for good friends, yet you want to 'date'. Which is it? You're far better off stating 'dating' as many women are on this site to do just that!
