Looking at your work, honestly you are for the most part doing quite well, but the bigger issues lay primarily with how you're putting your lines down. There are a few ways in which you're not really following the core principles of this course. It's not an uncommon thing, especially when we hit difficult patches - we compensate by putting less time or thought into something we may otherwise be comfortable with, so we can put it towards the things we find tough.

The issue comes down to your linework. Starting from the form intersections - which are, otherwise, a solid demonstration of spatial reasoning skills - I can see a bit of wobbling in a lot of your lines, which suggests that you are hesitating as you draw them. As discussed previously with the ghosting method, the focus is on investing our time in planning and preparation, and then executing our marks with confidence, rather than with hesitation. It seems to me that while you're committing plenty of time into the first two phases, you still second-guess yourself and execute your marks more slowly, perhaps pressing a little harder than you should as well.

It's not always this way - you've got some lines that are definitely executed more confidently, and as a result they come out straighter and smoother, but it is definitely a recurring issue.

Another issue I did notice in your form intersections initially (althoug hit applies across the board) is that there are definitely spots - mainly when you've got curves, like the edges of spheres - is that you start out with a rougher underdrawing, then trace back over it more carefully, with a sort of "clean-up" pass. This is specifically listed as one of the things you ought not do for this exercise](https://drawabox.com/lesson/2/8/cleanup). We want to make sure that we treat the original marks we put down as defining the form we're adding to our scene. Also, tracing back over lines causes us to focus too much on how our marks sit on the page, rather than how they represent edges moving through 3D space. Lastly, it causes us to draw more slowly and carefully, rather than confidently. The ghosting method should be used to add line weight just as when drawing the original mark - of course, just focusing line weight on smaller localized areas to clarify specific overlaps helps with this.

While linework continues to be a concern throughout your object constructions, you take a bit of a turn in the opposite direction. You start drawing more confidently, but you go back over your lines repeatedly instead of executing one mark at a time. It ultimately comes from the same place - not abiding by the rules of the ghosting method. We draw every mark following the three step process, planning, preparing, and then executing. One mark per line.

Now, that aside your constructions are for the most part quite well done. The forms are solid for the most part, and you've played around with a lot of complicated subject matter. In a lot of places you've really pushed yourself to subdivide your structures and pin your constructions down with greater specificity - although there are areas in which this could definitely be improved. You certainly do allow your rounded edges to stray pretty far from the straighter edges, and as a result some of them are at risk of losing some of that solidity, as you mention yourself.

The key to handling these is to build out boxy versions of your object first, then build out your curves on top of that structure. For example, a guitar can first be blocked out like this before you round out your curves. Building things out with straighter edges would have helped with your mouse construction as well. Curves are inherently complicated, so jumping right into them can make figuring out proportions and spatial relationships more difficult, especially with a mouse with as many complexities as that one.

The shoe is a similar case, althoug hit still came out quite well. The curves certainly are more vague, but it's definitely moving in the right direction, and the overall construction still holds up quite nicely.

Moving on from there, the rest of your constructions are quite solid, and I especially like the chair, the nintendo switch and the stylus/holder. The stylus holder has a lot going on, but you've built it up steadily, step by step, and so it maintains the illusion of being three dimensional nicely.

So, ultimately I am pretty happy with your results, but I do want to make sure that you fall back in line as far as the use of the ghosting method, and generally controlling your markmaking goes. I'm going to assign just a couple additional pages of constructions before I let you move forward.
