I am not an artist but those sketches look pretty incredibly good to me! Very cool you made it aboard, why this place isn't packed full of students your age right now is beyond me. Maybe that's something you eventually have a say in at some point. I wanted to invite you to an event I am hosting this week for newbies to the platform like yourself. It's a nice chance to get you rolling forward, meet more people, get more noticed, get upvotes all of that fun stuff. Feel free to ask any questions I like to be of help when I can here is the link: https://steemit.com/earthnation/@cryptkeeper17/win-steemit-upvotes-for-life-with-a-free-membership-to-steembasicincome
