Hello,
I'm a character designer, comic artist, concept artist and fellow lovers of DnD.
I'm gonna offer you my service on a per-image basis. The price I put in my quote is just a placeholder.
Char and Monster Design: 1 Character Full body, B&W Lineart (10$) or Grayscale (15$), and 25$ for fully-colored design
50$ for 1 Character/monster in a dynamic pose, 3 views (Front, Back, Side) -- a package if you want to Hero Forge your character.
And... just because I love DnD, I'm gonna give you a quick sample of my skill. I'm gonna design you one character in B&W for free.
If you're interested, just message me, and we can work it out.
Keep calm, and roll the dice^_^
Thank you
