I use Adobe Photoshop in almost all my paintings. Getting the "traditional look" is difficult, and something I struggle with as well. The key is stopping at a certain level of roughness so you preserve some of the brushstrokes instead of getting too tight with the blending and details, which is something I tend to do. I'd also recommend experimenting with various brushes and brush settings to find ones you like best (that also depends on which traditional medium you're trying to simulate). Good luck!
Hi, I appreciate you showing me this, however, you must have been mistaken. This image is not stock. I used stock photographs as reference to paint this, but I did not allow the use of this painting as stock. In your description under your piece, you state that you used the stock images "with permission", which I definitely did not grant, as this comment seems to be your first correspondence with me. It's especially concerning to me seeing as you stated that the piece you created is for a client, and not just personal work.
I strongly advise that you use the photos originally posted as stock by the respective stock photographers in your work instead, as using these paintings is a copyright violation. In the future, you may want to check with the artists you source your assets from before using them in your work. Thank you.
