Life drawing class (updated)

For our life drawing class on Tuesday 23rd April we went to Chapel field gardens and studied the surroundings, picked a spot and drew what we wanted whether this be organic or a structure of some sort, for me I did one of the big trees within the gardens, I drew this tree in particular because there has always been something about it that has intrigued me. I really like the formations and organic structures that it has. I used pencil to create this drawing and plan on using a fine liner graphic pen to experiment with it a bit. The drawing itself is of course not finished due to time restraints.

Below is a quick edit of the tree in photoshop, it's just a rough edit.
