You did a great job! Much the same for myself, these things can be a little nerve-wracking but what matters is you push through and have something to submit in the end. Glad I wasn't the only one who latched onto the sombre aspect of the picture - at a glance it is easy to chalk it up to being a sort of child-like joy with all the bubbles, chalk animals and the laughter but I definitely think there's another layer beneath that. :)
