I'm going to give some constructive criticism here.
It's pretty bad, good for a beginner but still pretty bad. there's no shading and alot of the features are.. disproportionate.
I'm not going to bash you hard or anything but if you really want to learn people,
like myself can teach you alot.
Final Review: Pretty bad from a professional standpooint. good for a beginner.
If your interested in art i reconmend looking into manga/anime to study how different artists shade. you can definately pick up some good skills from tracing aswell. not going to say copy someones work as your own. but the simple act of tracing free hand. allows your hand to get used to the movements needed to make certain features. i suppose. well thats how i learned.
