hi, I am not very experienced but I can see the eyes are the wrong shape, yours are almost Asian in slow, the characters are wider near the nose than yours, you are making Saun look angry when actually his face is friendly. have a good look at the eyes, watch the frown... it is not a frown it is the wrinkles of age and experiance... for me, this is what will make saun , suan, as they say, the eyes are the windows to the soul but what this means is they are one of the recognizable features of humans.

fantastic work.., texture makes a big differance, loks good.
