I tried to draw and paint from a photo I took last summer. I went with more realistic look using wet on wet, but since I lack patience it looks little bit messy. Few days ago I did same rose in ink, and I was much more comfortable and relaxed. 
It always looks easy while watching someone else painting, but when I try to do it usually doesn’t end well :) 

I used only three colours: lemon yellow, magenta and sap green.
