I'm sorry for not giving you feedback sooner. We like many aspects of your design, the action, text style, and the expression and illumination of the character. I personally am very fond of the character as a whole, but my partners are not as excited about it. They feel that the character is not personable enough. Do you think you can make the character's face more expressive and friendly.
Good job with those expressions, both very friendly and approachable. I will discuss with my partners and get back to you in a couple hours. I also like you choice of font style and color. Maybe you could try out some different positions of the character. For example under, over, or coming from behind the text. Try to make the character and text seem like a whole picture. I would also like to try to incorporate the subtext (subject immersion English) into the logo. See if you can fit it in. Thanks for all your hard work. I look forward to seeing what you come up with.
