I kind of combined info from Sue G class, and Deloris N classes to get the reflection to work. I used the triangle shape to make both my layer clipping mask, and then my cropping transformation which then enabled me to only have one stack of transformations. But I struggled to stay in that layer to design.
I am not yet very good at controlling my brush tool - so the first one I did with just some shapes to see if I could get it to reflect properly. Then the 2nd one I used the blob brush to make a compound shape which helped me stay in that layer, still going to try the brush set offered.
