Nice idea poorly executed. The problems here are multiple.
First and most importantly, the tilt of the horizon is very distracting. The subject in a photo please the viewers eye and being level is job one.
Secondly is the poor lighting forcing the use of a on-board flash. This has created an unpleasant glare in your central subject while under-exposing the cup.
There are other factors but to be competitive in these competitions, you must exercise basic rules of good photography. Hope this critique helps with future entries, These comments are meant to encourage improvements and heighten skills.
Best regards.
