close-up drawing

I took risks and my close-up project.  I didn't really know what I was doing. I just had a lot of colors and had an idea and started.  I had an inspiration for the picture but it was still hard. I wasn't sure how to make the shapes of the thorns but I made it look more balenced by using different sized and having different shades, and using different positions. 

I made original art by using my imagination when it came to the thorns. I liked how blue and green complemented eachother so I wanted to do blue thorns and added different shades and hues which made the thorns have different texture adding a visual appeal. There were darker parts towards the base which was the shadow 

how I developed my art making skill?  I had to make sure each thorn didn't look like it was going the same way or that each thorn was the same, I had to had a shadow on them. and on the branch I had to add different colors and high lights in the middle and darker parts closer to the thorns. in the thorn it was lighter and darker towards the base.
