New ink technique

I thought I might make use of today's 30min sketch to try out the technique Alison Woodward used in her youtube video.  If you didn't get to see it when I posted it last time, here it is again:

There's a tree near my house that produces long bean-like seed pods.  Before it makes these pods it has the prettiest white, orchid-like flowers.  The flowers are falling right now, so I decided to take one home and see what I could make of it in ink with a paint brush.

I drew it out first in pencil and then went over it in ink with a vey small brush.  I used my calligraphy ink again and diluted it with water to create the greys.  I thought it would be fun to do it outside, where I could also try one of the other small flowers in my garden (upper right).  The ink did dry very quickly, but I was able to wet it again in my palette with a little water.
