Picture - not perfect !?

So I was looking through my mom's camera ... (she's one of those ladies who carry them around with them EVERYWHERE) lol hehe. and I saw her pictures of me playing @ the show today (or rather yesterday) .. and in all of them I look kind of like .... emotionless or like not happy or something i dunno. just not good hahahdada. blahhhh but i duno.. like should I smile or something lol totally creep people out. dahaha.. I think I just look so intense because I'm concentrating on what I'm playing.... or I was having trouble trying to see the chords (forgot my glasses) .. lol and I'm in my own world......so like everyone is blocked out cept the music and im just playing along............... I dont know what kind of expression to put on? Maybe I should look out for my mom's camera next time lol and smile.... and then go back.. but I'm afraid I'll lose my spot and then play the wrong chord or note or something daha. wouldnt want tthat to happen!  blublub
