Tree ideas

I realised the other day that my rendering is pretty rubbish so I have decided to research different techniques and experiment with them in my sketchbook. I started off with various plans of trees and added a few perspective views in between.

So I started by drawing a few circles in pencil with a compass to use as bases. I then went over with a black pen.

Now my first thoughts about these sketches were that I definitely need more practice but they were a good starting point. At this point I also realised you only need a couple of trees you are good at in a particular style and then just resize them as and when. I found that the simpler the design the better which also made them easier to colour.
