20 sec Animation Storyboard

My current 20 second animation focused on the element of wind, the animation tells a story about a man who is hit by a draft of wind whilst reading a book, quietly and peacefully in his living room when he is hit by a big draft of wind that is evidently strong. He tries to keep the window shut but the wind keeps blowing it back so his solution in the end is to hold the wind using body weight, near the end the wind nearly budges open but the character manages to keep it shut then sighs with relief.

I will execute this animation using the traditional handing animation and then I will ink over using fine liners and then it will be cleaned in Illustrator and transferred to photoshop for each frame but I will need to do this in a systematical process,draw,ink and colour each frame after they have been drawn each day to save me having to colour and ink them after I have done all 240 frames because that will be really time consuming and it will take a lot of time from my hands, I think it would take up most of my time due to the effort and concentration that will have to go into to ensure it looks clean and presentable for my target audience.
