I am not sure if this critipue is ment for everyone,(I have also never writen one). BUT, I think its epic! It looks like something from a comic book! (I mean that in a good way) for just a sketch its pretty awesome! It is much more detailed then anything I have ever drew. I like the look on his face too ( lol) I also think he is kinda cute lol and thats pretty much all I have to say bout it Hope you don't mind/ like my feedback! (ignore this) ----> la la la la la la la la la (Just trying to get in 100 words )
This is a really nice picture with nice shading and anatomy. I can see that you really sketched out every body part, even the underlying ones. My gripe is though the left hand. The fingers are far too thick. I also notice that the hair is quite lifeless compared to the rest of the picture. The snout also looks a bit short. It's almost like seeing a human instead of an anthro.
I also love the minimalistic style. Could fit as a wallpaper, if expanded and maybe a filter on the beige part. You have really made a good piece, but there are stuff that needs working on
