Howdy. I'm 15 years old and I've been observing, and sometimes participating in, the pixel art community for about two years. As is true with most of the people that pixel art, I was introduced to it by video games I love. I really enjoy the interesting discussions that take place on this forum. It's good to find some good forums that aren't filled with Sonic edits. 
Anyways, I realize you all probably get a lot of threads from people new to pixel art asking how to become adept at creating pixel art. They usually receive a warm welcome, are told just to practice, and read some tutorials. I read those and took that advice. I've read basically every scrap of text available on the web and in my library on pixel art techniques. I've studied professional and amateur pixel art alike for hours on end, trying desperately to imitate the techniques and style for the sake of pixelling something decent and learning something. I've practiced so, so, so much. Thus far, in about two years, (on and off), I have created nothing but utter shit. I know it's not supposed to be easy, but wow.
I rarely share my work in pure shame as to the low quality. I think I've shown one work on here, but that's about it. I usually end up spending some hours on a project, decided it sucks and that I hate it, and deleting it. Sob story over, I have some questions for you all.
Is it possible that no matter how hard I may try, I'm just not meant to do this? That I'm just not artistically talented in this way? Also, where do you get your inspiration to make what you make? Music? Games? Do you just vomit it out effortlessly?
And how long have you been at this pixel art hoobie joobie? Am I too young to really do well at this?
Hey.
I'm just going to digest some information here and spit it back out, but might as well anyways.
Definitely stop studying... Studying imho comes after you feel somewhat happy with how your work looks. In my history I blundered around making HORRID art, but I thought it was great, and started posting it everywhere on the Internet. Boy, did that one hurt. I got fixed right up. Bringing me to point #2: If you cannot improve yourself by hard practice, self-critique and study, give it to someone else, post it on here. Rarely the artist is the best judge of his/her work for several reasons:
He/she has been staring at the screen/paper for several hours and can't see anymore,
Since it's you that's drawing it, you won't see obvious faults,
Since you're an artist, maybe, just maybe, you think it's perfect and unimprovable. Imo that's NEVER true, you can probably always go up another level. According to your own standards at least, as there is not such thing as good or bad art. It's only a form of expression. Whether people like it as much as you do is not really the point of art.
But, it sounds like you want to improve! So here's the moral of all that annoying text:
1. Practice your butt off.
2. Post it for others to see, and we will help you!

3. Don't try to imitate someone else's style. Don't worry about your own even. Ignore style, that will come. Right now just draw.
4. Feel comfortable on pencil and paper before you do this. (personal opinion, not necessarily true or that important, but it might speed up the learning process.)
5. Ages do not matter. I'm 13. I started at, what, 9? I blundered around until I got help. Trust me, it was horrible:

Just ugly.

Pillowshaded, total disregard to anatomy, bad color choice, not much contrast, ugly, and outlined without AA.

Let's not talk about this one.
But I started drawing on pencil and paper, and still do, from 5. It's my thing. I think I'm good at it. If you think the above are better than you can do, then it's because I'd had 3-4 years of practice, maybe one year of training. Now I take personal art classes with a professional, and we work on actual art-work, making framed pieces. Now my pixel art looks like this:


(after buying/reading the Animators Survival Kit)

Old and not finished....


working on this one now.
So, you see? I was horrible at pixels. Now I'm good. The difference is practice, posting it for critique here, (btw without pixelation I would NOT be where I am now.) art instruction, and self-critique. And maybe some talent, though I'm not sure.

Hope I could help,
