Thanks for comment :-)
Yellow is very difficult colour and my camera is very bad so this picture is misrepresenting.
In real this model is not too bright as it looks and highlights are done,but can´t be seems :-(
The shading is pretty good on this (I know yellow is a difficult colour to do) but the model itself is too bright and it's bringing it down. There also seems to be no highlighting, which such a bright model needs.
