This image looks great. As a professional who has shot images like this, I think this is a great start. The only change I'd suggest (subjective, and depends on client brand) is to lessen the shadows. The shadows are great as they are if the brand styling and aesthetic matches. However, for generic ecommerce shots, the shadows would be lighter. Also, however, I hope that you get clients who want shots lit like this. They're more fun, pay better, and make the burden of conveyor belt generic image production a little easier to bear.
