Nah man, you're good at drawing but if you did something original it would better, every single fucking person on this site has done a personalized sonic the hedgehog/anime drawing and its really fucking annoying, but if you drew something with you imagination it would be better.
Y'know, if you expand your imagination, you can become better and better. It's a slow and steady process, but trust me, it works. Trying out new things is fun, exciting, and trilling. And it's very helpful as well.
