Adding Designs into Illustrations

After teaching myself how to use layer masking, I have been referring to my technical notes a lot and using this technique with my new illustrations. There are a few things that can be tweaked, other than that I am very happy with this design. I see my designs working more as placement prints or using certain areas of one particular design as apposed to a full ' all over ' print. I have also tried to work on my style like Alex asked in previous tutorials, and I feel that looking back at my original illustration that this is a vast improvement.
