Tangle with R-K-I

I have changed my approach to Diane and Carolien's Weekly Challenge a little. I was using original zentangle patterns first where possible. Now I have decided to use any patterns  I find on www.tanglepatterns.com for the letters. I aim to choose them fairly quickly and to use one pattern for each letter.

What a difference some shading and a 'mistake' can make! I chose the patterns Reticulated by Livia Chua, Kitchener by Mary Sargeant and Inchworm by Lori Byerly. Three really fun patterns! I'm going to put my before and after shading photos here to show the difference. You'll notice there is also more black on the shaded example. It's said that there are no mistakes in zentangle. Doesn't it go something like no mistakes, only opportunities? That is the case here. I started colouring one of the squares as I had messed up the pattern I planned and added some strokes where I hadn't planned them. I decided to colour the alternate rows of diamonds and the border of the other rows. I quite like how it turned out. It makes Kitchener stand out whereas I felt it was getting a bit lost.
