Apocalyptic Horde Survival Vehicle - Finished Design Sketch

After finishing the blue sky sketching, I picked this one to make my final sketch because I still wanted my vehicle to have the feature of coach or wagon, and the half round shape was better to interprets this style.

But since I found that the vehicle looked longer than I expected, I made some adjustment based on the final concept I picked, and then started to put some equipments on it.

During the process I found that if I only used the keywords such as "steampunk weapon", I couldn't find many useful references to fit my vehicle well, but eventually I found that if I tried to find something like robots, it showed many interesting details that I could use in my design. Below were several photos I picked to add on my concept, but might changed or added more after I started photobashing.

Here was the outcome of my finished design sketch, and I tried to use colors from two references to make it looks more colorful.
