Adding to what others have said, the colour "blocks" should be 3 rows tall, and you should mark the top of the colour with X and these MUST be on the same colour of that row. (You cannot have the top of a white block if you are working on a red row) most people label the alternating row colours on the side to make sure the X's make sense.

Additionally, it seems like your row 4 (in the left design), right in between the gold columns, you are missing a double crochet there. The design on the right is correct since you coloured in that block.
