You made one which to me is similar (Guinomi), and I like that one a lot (the colour and the texture), but this one just does not work as well for me - i.e. the yellowish colour and the concrete-gray. Please do not let my comment put you off though, I encourage you to continue in this line.
The single colour brown with different shades work extremely well.
If you did it in bright colours it would have spoiled it for me.
This reminds me of what someone recently told me: If you have beautiful form, you do not need much else in terms of glazing.
