Please don't misunderstand me - I only said that you need to add shading to the frog is because you have shading and highlights on your text. Because of this diference the logo does not feel as uniform as it should. So right now you kinda have depth on the letters but the drawing looks kinda flat. So make it either everything is flat or everything has depth with shading. But since you did a really good job with shading on the letters - I suggest you add it on the frog as well.
