Okay, let’s break this down. Dmitry has a mix of artistic and technical skills, which is great. However, his experience is mostly in video games and concept design, which might not be as high-demand as other industries. Location is Vancouver, Washington, which is not a major hub for 3D art. Considering his skills, I'd look at average rates for 3D artists in the US. According to Glassdoor, a junior 3D artist in Vancouver can earn around $40-$60 per hour. Since Dmitry has more experience, let’s bump it up to $75 per hour, which is still on the lower end of the scale.
