Its good bro but it needs shadow, look at my paintings to see what I'm talking about, you need realistic shadows otherwise it looks unrealistic.

Your approach is good and you are doing it well. If I may, I would suggest to define the light streams a bit more by putting two pieces of carton or paper together, leaving just a tight space (about 1 or 2 mm) left and spray into this space from a certain distance and waiting a bit to let paint dry. Then your light stream will be much thinner and you will get a better lighting effect. Keep doing well and congrats for your work. I invite you to see my work, as there a some examples of what I mean :), although mines are not perfect too :)
