Alright, you've got some good starts here, however they need some work. Here are three tips that you could probably use: 1) go through with your lines, most of your lines are very broken and Scratchy looking (it shows a lack of surety and confidence in your strokes) (how to draw basics course lesson: simplify to CSI would probably help)) 2) line weight, your line weight is all over the place and in addition to the prior issue it makes your figures incredibly difficult to read (again check out protons drawing basics course the first couple of lessons really help with this) 3) as it pertains to today's challenge I think you could really benefit from simplifying to primitives (cylinders, boxes, balls, etc.) rather than focusing on the contour (outside shape) it will really help you to "digest" and better display anything you encounter. Sorry for being long winded, I hope that this helps.

Wow! This helps a lot! Thanks mate :)
