Hi,
i had a big personal project about a mobile game idea last year, so i had rich experience in creating such assets! You can see 2 of them in my portfolio sections. I would create them as you wish with all the details you want . I could deliver you more works from that project if you want!
I am very new in Freelancer and doesn't have that much clients here but i already have over 6 years experience working in-house as a concept artist for browsergame company (Gameart Studio); Silver Style Studio in Berlin and Bluebyte Mainz (Ubisoft) in Mainz for the AAA PC-GameTitle "Anno 2205".
If you can consider me i could give you a discount!
Thank you so much for your valuable time and consideration.
