If I'm taking too long to answer any declination message, it's ok, it's normal. I have currently like 50 pages of messages, people like to ask and complain a lot, some just like to ask too many questions, and some just like to tell me "Y U HATE ME" really, it's not personal, it's only business. Maybe you really need to go check the galleries you're submitting to, and read carefully our submission guidelines. Anyway, it's just a rejection, not the end of the world...oh god, I am so tired of explaining the same things again and again. -.-
Cheers <3
