The Wiseman Meets T-ship

I am uploading here the final scene of my project for this year's Concept Art course with SoftUni. The course was memorable in many ways, and Dimitar Katzarov - the tutor - made a fascinating show of Blender's endless possibilities...
The scene depicts the "Wiseman" - a representative of struggling Humanity - on his way to meet the "T-ship" - a mechanical entity which has acquired a very high level of reasoning - for the sake of negotiating a contract for mutual help. *(For more info about T-ship pls refer to my artwork:

I did the composition in Blender and then added detail and overpainted the scene in Photoshop.
