No program is a jack of all trades, so (if you have enough money!) you have many tools and select according to their strenghts and the task you want to accomplish.

From your gallery I see that (at least for now) you are into portraits. I think that DS3 has more than what you need now (especially the Advanced edition which allows you to hand tune 3Dlight behaviour). Even renders more complex then portraits (e.g. showing your ladies in a room with furniture, some plants etc.) are well withing DS3 capabilities.

Should you want to create large scale external sceneries, you are better off using (for those cases) tools like Vue or Carrara.

Vue is more user friendly than Carrara, costs a truckload of money more and does not interate easily with Studio; Carrara has the bonus that can handle Poser content natively and DAZ works hard to make inter-operate with Studio.

You can try Vue downloading the Personal Learning Edition and you have a 30 day trial of Carrara.

Your mileage WILL vary...
