It isn't a shame. Everyone can draw, it's just like (>
)Sports, practice makes perfect, and there will always be someone better.
I haven't put any of mine up but when I do maybe you'll feel better.
In any case, Drawing isn't about whose better, it's about creating an original piece of art, one you can call your own and be proud of. It's about bringing out the faint sparks of beauty in the world and letting them shine.
Art comes in all different forms and just because there are better drawers out there does not make you a bad drawer, nor does it make you a bad person, IT makes you human.
Everyone has to practice to get where they are, and to get better they have to keep at it.
You'll get to where you wanna be and then everyone else will e better too, you'll be amazing and still you'll feel insignificant because there will always be people better than you.
So love your art the way it is and forget that there's better out there. Just draw for you and the talent will build on itself.
