Hello, how are you? My name is Mar and I have a lot of experience working with many styles of illustrations. Im still have not the chance to work for a board game, but I can do any style, as you can see in my portfolio, I am capable of a big detail as the examples you give.
If you dont find in my portfolio anything in the style you like, please let me know. I'm sure I can show you more examples or I can make you a free sketch.
You can write to me and we will discuss the details.
If You have any questions email me..
Thanks for your time, Mar.
