Hi VAIBHAVSHAKYA!

First of all I'm seeing little pencil or ballpoint sketches in your work. For an example, on the llamas page (that's what I think it is) there is a box surrounding the legs . You can put dots with your fineliner but I don't think you can draw it outright expecially with a different pen (which is what I think you used.)

Your appendage sausages look alot more like cylinders. If you watch the lesson video he says the reason why you use sausages is because they convey gesture.

I recommend you draw bigger for lessons like this one. An animal is so complex so try to maybe only do 1-2 animals per page and if you want to draw more animals feel free to do so.

Also you shouldn't be doodling or doing any other exercises other than the one your focusing on for that page. One of the llama pages has some warm-ups on it.

Your linework is pretty messy is some areas. That may be because of your small drawings or little confidence. Sometimes I can see your trying to go back over an area and redo it, but don't do that. Remember CONFIDENCE!

Your added texture is also messy probably because of your small drawings.

Your additional forms are pretty good. Some of the forms are a little bit 2D-ish, but the majority are nice!

For how your drawings turned out, lesson 5 isn't really the most visually appealing lesson, Even though it doesn't look like a Mona Lisa (if that's your style), you still got something good out of this lesson. Draw A Box isn't about making pretty drawings. Draw A Box is about becoming a good artist and developing the technicals skills needed.
