Well, first of all the overall character design certainly is pretty neat! Unfortunately though the character does not really look broody or gloomy to me - because the glasses and the smile makes him/her/them look really laid-back, observant, abstracted maybe. I'd suggest that you take away a bit of the smile (line on the beak), right under one of the goggles and maybe tilt the head a bit more forward. I think, this will help you achieve more gloominess! :)
