|Looks like you are learning about lighting, so I will offer some advise I hope you find helpful.
1) The light is coming in an making some very noticeable shadows. Photos like this benefit from soft light, so try diffusing your light source with something like a bed sheet.
2) The half reflection on the table isn't too appealing, so maybe crop it out, or use a surface that is even more reflective.
3) The pink background doesn't compliment the yellow well, try purple instead, as it's a complimentary color.
4) Make sure you have super sharp focus on the banana.
Bonus) Two objects can be hard to work with photographically speaking. Often odd numbers seem to work better, so try this out with one or two bananas.
