Wow, no. You can't just rear your head at an artist who is making something for FREE and demand more. It's THEIR time they're sacrificing to make something for others. How can you bluntly say you'll be mad if you don't get something for free? Learn some damn respect, it's just disgusting how you're treating this situation.
How would you like it if someone got mad because you only opened one slot for something free that you put your OWN time into? If someone gave the same reaction to you that you gave to this girl, I'm sure you wouldn't like it. Worst is you pretty much forced her into her decision when she clearly stated that she doesn't have much time at the moment at all.
It's really such a selfish thing to do. People who act like you are the reason many people shy away from opening FREE requests.
