Awesome pens and the lighting has a nice soft/diffuse feel to it.
A few comments to take it to the next step:
- you have a couple of dust bunnies on your sensor (top right corner and right above the pens left end in the landscape shots),
- the portrait-oriented shot seems a tad out of focus (or maybe a heavy crop?)
- the overall white balance seems off. I quickly reprocessed one of your pictures to show what I mean.
