Good Character Design
Firstly its good to see you submitting art that isn't made in Paint.
I like the use of the two colours but maybe I'd suggest some more shading and maybe a shadow. Also one of the legs seems a little disformed and appears to bend the wrong way.
From the description I see that you made this a few years ago and you appear to admit that this isn't your best work. Can I suggest that in future you only submit your finest work. This would help if you wanted to get scouted in the future. Though I have to admit that for a drawing made by a twelve year old it isn't half bad.
In conclusion, this is a good character design but it could be improved and I'm sure you are better now.
Keep it up :).
