Help Needed

I have a small tree that has been pushed out by the tree next to it. I have now cut the tree to the right back creating a gap. 
 

My question is how can I encourage the small tree to grow over to the right now and again a good shape?

 

Thanks in advance

Looks to me like a photinia bush and something more vigorous growing behind it. Things grow with sunlight, so depending on the direction of the sun, depends where you will get more growth on your bush. 

 

If your smaller bush is being shaded out by the bigger bush then there will always be a struggle for the light. Looks like griselinia to the left and cherry laurel or rhodo (but more likely cherry laurel) to the right, behind. Both of the structural shrubs/bushes at the back are more dense and faster growing than photinia, that is not to say it won't grow, but the smaller shrub will need more feeding and more attention than the bigger bushes.
