This is why it's absolutely fatal for some well-meaning person to come by and tell you that your first efforts are rubbish. Believe this person, and you will give up. Beginners, like children, thrive on encouragement. Disparagement and brutal criticism make the creative urge wither and die.
I've found this to be true in every area of endeavour I've had a go at. I was pleased as Punch with my earliest attempts at making jewelry. I've still got some of those pieces, and no one could have guessed their maker would go on to have a career as a designer jeweller (I'd find it tricky to know what to say if a student showed something similar to me with quiet pride). The same is true of my first novel and my first book covers - but luckily the joy of creation spurred me on to better results.
Do the best you can, and don't let other people put you off. And never blight anyone's first tentative green shoots. You don't know what they might grow into if let alone, and it might be something amazing.
