to add text to your ellipse you can clone your main ellipse and modify the height by dragging the top handle so width and height are the same values - resulting in a circle. Then you type your text, flip it, fit text to curve and drag the top handle until the height matches the one of your original ellipse. To be on the safe side, you should scale the circle by 20% before you fit the text to curve, so the text will not touch the edges...
see sample below.
In addition you should watch your shadows. In your drawing the shadow in the hole is from left to right, but the overall shadow is from front left to back right - doesn't match.
Shadows are tricky. If you can try to avoid a 100% black shadow - nowhere in nature a shadow is really 100% black ;-}
Adding a tiny outline to add a highlight and a shadow to the edge of the hole will enhance the image a bit. Just copy the shape of the hole, set outline to 1 pixel, outline color black, convert lines to shapes, add a linear transparency with 100% at the center point, clone the shape, flip it, change fill color to 70% white.
