Boy are you ever hard on yourself.
Come on take some credit.
Did you trace the WHOLE drawing?

I think you did a super duper job.
Do you think an artist does so well when they are first starting out. I think not. It takes practice, practice, practice, and with practice comes experience.

Believe me when I say, that in due time, YOU WILL be drawing pictures like this 100% by yourself. It takes time, patience and confidence in yourself.

Don't give up, put your whole heart into it, if this is what you love to do, go for it.

Looking forward to seeing more pictures in the near future.
