Well, for starters, you should just draw what you want, others shouldn't affect what you do, and believe me, only thinking about other people's work is only going to hinder you, you don't get to be good overnight, and being an artist is a long struggle, one you're never going to be satisfied with.
The best way to deal with that feeling is just drawing, and not comparing yourself, yeah, maybe other people are better, but other people aren't you, and they will never be as unique as oneself, remember that.
Now, if you want to make a difference, start drawing A LOT, don't look back, if you think what you do is ugly, then try to see what you can do to make it better, watch other drawings, try to give it a spin, one only you can imagine.
I can't promise it will help soon, but I can assure you it works, and I know I'm a terrible example, but with time, you can see all of your mistakes, eventually.
¿Y que no hablas español?, ya se que tu gramatica es interesante, y te he visto desde que empezaste a postear en /pony/ (hasta cuando cambio a /show/ y volvio a /pony/) asi que has estado aqui un buen rato, eso me hace preguntarme, ¿desde cuando dibujas?, no se ve como si acabaras de recoger el lapiz sinceramente, ¿ya llevas un tiempo no?
