It's not bad, you know- you got the shine of the fruit, and a good go at shadow-form.
I've only done a few coloured pencil pieces and those a decade or so back, but this is what I remember:
-Good-quality coloured pencils because they have a higher pigment load- get the best you can afford if you're wanting to do this for real
-Think about the complexity in any one colour; for instance, "purple" on a round object near other coloured objects is not just one hue- it is
various blues, reds, pinks, darks (such as green or winey red) so you need to think in a hue map of layers manner
-Because good CP is done in up to seven or eight layers, you need a good toothy paper, and to use a *light* touch every layer
This artist is a queen of CP- you could do worse than to read/watch and study what she does and how she does it and then adapt it to your own vision:

It is NOT easy to "get" first try out of the CP box- but it *is* a terrific medium, and wonderfully contemplative in which to work. It's a meditative medium.
Keep going- you're doing well, and will get so much better!
