Perspective

My little shelf thing that I never put on my wall became very useful today for a little practise in perspective drawing! It's an "almost" cube if that makes sense, and I am feeling determined to improve at gettin perspective right because it is subject that really Appeals to me. So I need to practice more and had a half hour free today and did some quick sketches. They are a bit wonky but I can only improve with practise and I have to start somewhere! 

Sorry about the photo quality il use my scanner from now on when I get it set up :)
