It's pretty good!
Hey I feel bad for you to lose your brother. That's really tragic. My advice to you would be to take as long of a break as you need but I think you did good at this and you have some potential as an animator! As an artist I'd like to say that you are talented, you did much better than half the people on this site, and would probably do very great at flash in the future like collabrative efforts and stuff since im sure that having to do everything else yourself must take away from the energy you'd normally have to do great artwork... idk, I'v never made flash myself really. But you certainly shouldn't give up especially if its something you like doing.
