Hello, I mostly do medieval fantasy art but I can do sci-fi too.

Here is my portfolio: https://www.artstation.com/santiagohertzan

And these are book covers I did before: https://www.amazon.com/Mage-Unmasked-Greenwood-Academy-Book-ebook/dp/B09TYMJB1D

Feel free to send me a message if my style suits what you are looking for.
