Without a before picture, there's no way to tell if you've improved any.
I will say, however, that there's room for improvement. Learn how to draw from life and references. Learn how to use perspective systems (one, two, three point). Make study of anatomy a priority if you want to focus on character design. A good understanding of the human form is considered essential for art. Look up Bridgman's "Constructive Anatomy" and Loomis' "Figure Drawing for All it's Worth." While it is helpful to understand some methods for constructing the human form, it is no substitute for reference study and observation. It cannot teach you what a face looks like, only how they recreate it artistically.
The people who are telling you that it's perfect or awesome are not doing you a favor. It's empty flattery, nothing more. Listen to those who tell you how to improve and drown out the din of those who would belittle you or deceive you with kind words.
