Practice makes better, as I say.

I hope that you don't mind me putting my two cents in, but if you keep talking down on your work like that—saying things like "It kinda sucks," "This looks horrible," "My art isn't as good as theirs," yada, yada—you'll never get anywhere. You'll blind yourself to any improvements you've made throughout your years as an artist and you'll face nothing but disappointment after disappointment. I've been drawing for over twenty years now, and while I can't make you take my advice, nor am I trying to force it on you, I suggest that you at least consider bringing your opinion of your own work into a more positive light so that you're able to see how far you've come instead of making yourself believe that you've gotten nowhere, and so that you're more happy with your art later on down the line in the future. When you draw, embrace your mistakes and learn from them! Most importantly, have faith in your talent and skills. You're not a bad artist, but you will be if you continue believing such a thing.
