Hi This is Tutun,
I went through your job description and much excited to know more about the project. I have designed many games for unity and other engines.
I have done many games in various styles from cartoon, realistic, fantasy, whimsical, futuristic, Sci-Fi to medieval and many more with their gaming assets and UI/UX. Now what should be the style for UI and what should be composition of elements, this all depends on what your game is and who is your target audience.
I am excited to know screen details and little about the game.
I assure you that my skills will help you to create outstanding graphics and I will bring your ideas or concept into my illustration and deliver the art what you want.
Throughout the process we will be keep communicating and will keep getting feedback to get the perfect outcomes in the least time.
I have been doing graphics designing and characters for over 10 years. And have done 1000+ characters, a lot of environments, UI and all other graphic elements for games, novels, animated series and more. Have worked in different styles from simple vector art to highly realistic illustrations.
