Hi, firstly you can add more than ine image to an album in Imgur so then you only need to post one link.

Your lines are looking pretty smooth so good job. Be careful to CV take the time to place you pen at the right point at the start of each line, rhere is a little bit if fraying at both ends. There is also a little bit of curving. This could be because you aren't using your shoulder, or some people just have a natural curve. You could try curving purposefully in the other direction to correct it. With time yourbrain should start associating that motion with straight lines.

Overall I think this is a really good start!

Good luck on the rest of the lesson
