Probable adopt #6.
The last red book animal from my graduation project was the European mink. His initial concept was significantly different from the final result, but I had to do it in such a way as to get the approval of the thesis supervisor.
At the moment I am very busy with heavy official work, the 2022 inktober, the redwall inktober. Due to the huge workload, I won't be able to deal with characters for sale until November.
