Orchids a sketch in graphite

Having been drawing for weeks now in my sketch book as a preliminary step to the portraits, I've decided I like doing graphite so much that I wanted to do something a little different on my day off. Might have to take another day off this weekend and do something else not art related. This was the orchid I purchased a week ago and I've been trying to find time to paint it again but this did not happened yet.
Here I was trying to look at edges and try and get depth to the drawing. Fun stuff!
