Sketching a tree

I am trying to draw a little bit every day. I really feel like the biggest part of it is practice. I am trying to achieve two things - understand perspective, shapes and shadows, and practice various strokes.
I also feel like knowledge is part of it too. There are tricks that I am learning, that really help understand the concepts a lot better.
So today I finished my one point perspective drawing... Here is a video that really helped me in this...

I also watched this video by the same author that inspired me to try and draw a tree. I really felt like I did a whole lot better than I ever did! I just drew one from my head and I feel like it was a good practice for shape and shadows.

The third thing I did was just listening to some music and drawing non stop with various strokes. It was fun and I am practicing to have a steady hand.

All of this is baby steps, but I see some progress. Not so long ago, my level of drawing was about third grade, so I've got room for improvement there. Just thought I would share, because I know nothing about drawing and now I am trying to self teach myself a bit. This is to monitor my progress and hopefully to show that anything is possible! :)

One point perspective

I am honest in this space - I don't know how to do anything. But I want to do everything. So I beg my grandmas and mom to teach me whatever they know (knitting, crocheting), and then figure out the rest via books, online, or common sense (doll making, photography, cross stitching, embroidery, miniature making, etc.) So what comes out of that is far from perfect. I attempt it anyways, because this is how you learn! And also, I wouldn't let anyone tell me that I can't do it. I guess my ignorance is my blessing in this case.
So not so long ago, I decided I want to learn how to sketch. I like pencil and I want to be able to sit down and quickly jot down something I see. I have been playing with it in a more or less regular basis. Today I decided to look for some help online and I found these youtube videos about one, two, and three point perspective. So I took a photo of a street in San Francisco that I took a year ago that was one point perspective and began figuring it out. It is hard is all I can say! Seriously I am going to take some classes or something once I am done with dental hygiene school...
Anyways, this is my work in progress, which my husband said looks nothing like San Francisco or one point perspective. Haha! Oh well, I feel pretty good considering it is my first try and I know nothing about it... Actually overwhelmed is a better way to describe my feelings... Maybe the other side of the street will look better...

P.S yeh, I know, the street is completely flat, in reality it is suppose to curve up, but that is beyond my abilities at this point! :)
