Isometric Map Illustration for Video Game

Hello,
I'm looking for a talented digital artist to create a high-quality, custom isometric map illustration for a video game.
Artistic direction
I'm looking for a colorful, detailed, stylized isometric environment with a polished, semi-cartoon 3D appearance, similar to modern Tycoon and City Builder games.
I'm NOT looking for flat vector illustrations, minimalist artwork, or comic book styles.
I have created preliminary concepts using AI to help communicate my vision. The attached reference image represents both the desired artistic style and the layout of the map.
Main requirements
- Create one complete isometric map illustration featuring 13 distinct buildings.
- Preserve the exact building positions shown in the reference image.
- Make every building visually recognizable according to its function.
- Create coherent roads, vegetation, terrain, textures, and architectural details.
- The environment must NOT be an island. Water should only appear in the harbor area at the bottom-right.
- Remove all labels, numbers, legends, and interface elements from the final image.
- Deliver a high-resolution PNG, preferably 3840 × 2160 pixels (16:9).
- The final result must be a single 2D illustration. No animations, interactive features, or 3D models are required.
Important technical detail
I will implement interactive highlighting effects myself. Buildings and their surrounding areas should therefore have clearly identifiable boundaries, allowing me to create masks or outlines later.
Artistic approval
Before starting the detailed final illustration, I would like to review an initial sketch or simplified visual concept to validate the artistic direction.
At least one opportunity to provide feedback should ideally be included.
Commercial rights
The artwork will be used in a commercial video game. I require commercial usage rights, including permission to modify, reproduce, and display the illustration in the game and promotional materials, without additional royalties.
Future collaboration
This illustration is part of a larger ongoing project. If I'm satisfied with the result, there may be opportunities for additional illustration commissions during development.
The game will also include a dedicated credits page acknowledging the artist's contribution, using their preferred name or professional pseudonym.
Your proposal
Please include:
- Examples of similar isometric game environments you've created.
- Your proposed price for the complete illustration.
- Your estimated delivery time.
- The number of revisions included.
- Confirmation of commercial usage rights.
I'm open to working with artists worldwide.
I value artistic quality, communication, and a style that closely matches my reference image.
I'm happy to answer questions or provide additional information.
Thank you!
