Concept art for a game with playful style

I am a freelance game developer. To display my skills I use a game as showcase. Recently I have decided to update my game visually. What I am in need of is a concept artist that can draw basic but creative concept art for a 3D modeler to create. I have attached an image of what I am looking for. Basically front, back, side and isometric. I'd also like one of the views colored. I'm looking for bright saturated "happy" colours, such as used in Blizzard games (Overwatch for example). It doesn't have to be pixel perfect drawn or colored but simply conveying the style of the unit and thus game. This style should be a mix of cartoony/realistic for maximum appeal as you can see on the attachment. In general we are talking about the following: - Around 15 to 25 units (Some units are near-identical) - 5 game backgrounds/decors - Widgets in the same style for the menu screens and dialogs. Also, all associated rights such as, but not limited to, intellectual property, copyright and legal ownership will need to be included. Please start any bids with the name code-monkey so I know the entire brief has been read. Thank you for your time.
