Okay, first off...
I am so sick of hearing people say "tell me if I should continue this."
First off, a good flash takes a serious amount of time, some people take months before submitting. You should be creating a flash because you enjoy it, not because other people tell you to do so or not to do so. Unless its homework, I sure as hell wouldn't want to waste 2 months of my precious time working on something that I wasn't very interested in or delay something that I want to do but can't.
Now that's out of the way.
The graphics, were surprisingly pleasant. There's alot of good color tone and well place usage of the gradient tool. However the lack of a good background really hurts the graphics score.
Normally polygon type characters seem generic with the exception of robot and mech animation. I don't know if your character is organic or what, but this design works.
I can tell you got the tree from the Tree Tutorial on Newgrounds (nothing wrong with that, because its an excellent guide and I'm using it right now for some forestry elements.)
I wish I can say more but I just got back from a long midnight shift.
Here is some advice,
-The world isn't going to end, take your time on your flash and don't feel like you have to finish it in two weeks or so.
-I have some tutorials under Favorite animations on my profile, I've found them extremely helpful and you will too.
-Never EVER say "If you really want me to, I'll finish it". I don't care how many authors say that on teasers. That just tells the audience that you haven't worked on anything passed a trailer and will brush off your work as another failed trailer.
---NOTE: If you want my opinion, If you like your concept, got ideas, and know how to execute them, than you know my answer.
I wish you good luck in the future.
