The biggest issue at the moment is the anatomy.
The left arm is much longer than the right. The pose is also very uncomfortable and stiff. Try standing like that. Before you start making the sprite, plan out the pose first-either on paper, or using yourself as a real life model. Now, I'm sure you're not a raccoon in real life, but the character shares lots of traits than you can use to judge: two arms, two legs, a torso, feet, a head, etc.
As for the goggles, I thought it was a bowtie. Look up reference pictures of goggles- even a white highlight can suffice sometimes. Maybe try putting them on his head like Eggman in SA2B?
If your intention is the TFR style, the shading you have on the leg is unnecessary. You also have too many colors, atm.
Try to shoot for eight colors (blackish color, white, one blue for eyes, two grays, and 2-3 browns. You can use the lightest brown for cheeks and make the goggles blue or gray. TFR style is very animated and simple.
The character design is simple and effective for the style, it just needs to work on its execution.
Also, try giving life to your lines. Right now you have straight lines and circles, really.
Both of these characters are pretty generic, but the one on the right has much more life to it than the left. Colors aren't the only thing that give a character life.
Don't give up! I joined here at around 13 also, and if I had learned anything, using your age as a crutch gets you nowhere. Don't take any of this personal, consider only the advice and critique from these posts, and use them to better your sprite and overall ability as an artist.
