i haven't seen your work so i'll just mention a common mistake with beginner quilters and its fabric pattern scale.
some beginner quilters get caught up in all the beautiful prints on the market and put them all together in one quilt.
when working with prints its best to have large or medium size prints with small prints and blender/solid fabric.
this allows for your eyes to rest on those sections and see an overall design instead of getting lost in a sea of prints.
