In this question, I want to say about the drawing which is less artistic and more problem solving. But problem solving is not adjective, as contrast to artistic.
Is there an adjective for problem solving?
With the addition of a dash, problem-solving can be used adjectivally before a noun. In fact, a lot of similar adjectivals can be formed with the active participle ending in -ing: habit-forming, all-encompassing, ever-increasing, etc.
English is quite flexible on the way different parts of speech can serve as adjectives. Note that when numerical expressions are used in this way, they are never plural in form. There is a strict rule in English that adjectivals may not be pluralized. That's why you see forms like two-mile hike, three-minute phone call, twenty-year-old girl, etc.
