Your good but need to be a better showman
While those traditional animation exercises on this site aren't too common you can still make something even less common and make an even bigger impact on your audience.
You have some substance there already to your work but you can make your work a little more flashy to stand out above everyone else.
Thats not to say that you should make your movie purely just pretty graphics because that would be hallow and would only serve to entertain graphic whores.
It's important to make your work entertaining in and of itself since even with it's imperfections and than polish it up when it comes time to.
When your happy with your movie than that means your done and ready to show your work to everyone warts and all.
There is no tangible way for me to explain how to make something entertaining since what might entertain me might bore someone else to tears but you can still do things to make your work different from what everyone else is doing.
Coloring in your drawings will make you stand out from all the other people on this site that do traditional animation here because i notice most of the colored in animation in your short collection of animation exercises were done in flash rather than on paper.
I'm not saying piss away all your money on cels and make backgrounds but you can still ink in your drawings than color them in with markers, water color or coloring pencils.
Than you can than transfer your colored in art work to photoshop and erase any part where you didn't draw anything in and combine it with maybe a background you did to go with your drawing.
The background is just something extra to look at but it must not compete for your characters attention instead backgrounds are used to make you pay attention even more.
Your on a positive step so far. you took a year off to learn before you showed anything off.
