It depends upon what you are going to light with the set-up.
The pen, having some highly reflective surfaces, is showing the shortcomings.
The hard-edged shadow shows that the light is mostly a point source hence the hot-spot on the top front. It is also picking up the texture on the metal - not something you always want with macro.
And the reflections of light and dark along the whole of the pen - especially around the front end - are rather messy. The important part of this shot is the lettering on the end so you should be working to sculpt it more. To deliniate the embossing.
You would do better to build a small light tent with tracing paper to soften the light, reduce texture and reduce lighting contrast.
If you build it right you should not be able to see any reflections on the pen.
You then use strips of black, white and grey card to put shadows and highlights where you want them.
This, of course, is a suggestion for the pen.
Different objects require different lighting solutions determined by what qualities you want to show, what you want to hide, and what each is to be used for.
