So I've been thinking a lot if I want to work on my piece or should I declare it as a finished piece. I decided to go with a more stunning looking piece. So here's my update:
I've touched up the piece quite a bit I couldn't resist myself to do more with it
So I've changed a lot of parts on the render, added a bit more mist to it.
Also I made an additional concept sheet to summarize my process:
Overall I'm really satisfied with this project It's been quite fun doing it, I think I've learned a lot and also learned a lot from the responses and from people here.
Also I want to thank @volenck, @hebronppg, @raedrob and @obra-kalla for their responses, encouragements and contribution to this project with their advices Thank you guys!
