Alright, a whole lot of locked pieces with a few blocks involved. Look over the entire cage of pieces and see if you can find some pieces to unlock right off the start. The more you can unlock, the easier this level will be. Remember, the goal here is to create 7 color bombs (1 is pre-frozen, so really only 6), but the only way you are going to do that is to clear space. Try to focus more on the upper half, but unlock pieces at every opportunity. If you can create a vertical striped candy, those are ideal for plowing through the locks to give you more to play with.
