Questions & Answers about Я хочу нарисовать красивый пейзаж.

Why is it нарисовать, not рисовать?

This is about verb aspect, which is very important in Russian.

• рисовать = imperfective, focusing on the process, repetition, or ongoing action
• нарисовать = perfective, focusing on completing the action

In Я хочу нарисовать красивый пейзаж, the speaker means I want to create/finish one picture. That is why нарисовать is natural here.

Compare:

• Я хочу нарисовать пейзаж. = I want to draw/paint a landscape.
  
  • emphasis on completing it
• Я хочу рисовать пейзажи. = I want to draw/paint landscapes.
  
  • emphasis on the activity in general

So here, нарисовать fits because the sentence refers to one finished landscape.

Why is красивый spelled with -ый at the end?
