Sweet Home

This is my big project with the color pencils and never tried shading with color pencils before.Just gave a try and  liked the way it has come out..ana i can say i have shown much patience than before to see the final output.

Donno if i am using these pencils in the correct way.. i gave nearly 2-3 coats on each color to bring the brightness..is it correct? or my color pencils or bad?
Any suggestions are welcome... :)
