Screen writing- Idea

My idea is basically an artist who loses his inspiration and finds it again by gaining the ability to enter paintings literally. The protagonist Michael has a hard life and not much to live for, he works a dead end job and only has one friend really, Shannon. Shannon is almost a polar opposite of Michael as she is successful and easy going, they get along well regardless.
The original 10 step outline for this film was:

1. Michael is doing a painting in his art studio which is in his basement, he is very good and is finishing a really good landscape.
   
2. Michael gets up and does his daily routine before going to work.at work Michael does not fit in and is constantly being shouted at and scorned because he is the only non-Italian in the restaurant staff.
   
3. Michael then gets coffee with his best friend Shannon after work, he tells her about all of his money issues and how he will potentially be evicted from is house. Shannon offers to pay his bak rent and help him out but he refuses and gets angry, the two compromise with her paying the coffee bill.
   
4. Michael returns to his basement to do some more painting but he has lost his inspiration and in a fit of rage he trashes his workshop.
   
5. Michael is getting shouted at at work the next day and while he is, he stares at a painting of a forest and all of a sudden finds himself in the forest. he explores the forest and finds a picture of his basement as he left it, upon studying this he finds himself in there.
   
6. The same thing happens the following day in a lettings agency when he is being told he must pay off his back rent or face eviction, this time it is a marina but the events transpire in the same way as the forest.
   
7. Upon returning from the marina Michael has rediscovered his inspiration and begins work upon his perfect scene of a log cabin in the woods.
   
8. The following day, Michael goes to see Shannon before work for coffee and cant help but tell her about his new found joy and where it is coming from. she cannot believe him and the two get very angry, Shannon because she thinks Michael is making fun of her, and Michael because he cannot show her his power, Shannon concludes he isn't making fun but that he was just dreaming.
   
9. Michael leaves the coffee shop and heads to work, only to find he has been sacked due to ‘hardly being there all day’ when he was getting shouted at. he then heads for home to find an eviction notice on the door of his house, Michael tears this off and immediately goes to his basement to finish his art, he pulls out a chair to reach the top and the chair gives way, leaving Michael hanging. Michael has hung himself. 
   
10.  Michael hangs from the ceiling and drops his paintbrush which has a black paint on it, we then look over his painting and see a newly added silhouette, then we see a slight movement, or perhaps it didn't move, the point is to make the audience decide. 
    
    Although there are some differences as the script has developed this is still the basic plot, although I am thinking of adding a third painting scene instead of the intended original 2.
