Hey there! Welcome to Drawabox. One of the great things about Drawabox is that it'll give you the foundation you need to fill in those gaps in other tutorials as it deals with the very fundamentals that those resources tend to assume as prior knowledge. Regarding your tremor, I had a quick scroll through your album and there's instances where I can see you're capable of overcoming it, so try not to lean on that too heavily as you can definitely do it.

Starting with your superimposed lines, your straight lines are quite straight and confident. You've done a good job lining your pen up with the starting point and thus reducing the amount of fraying present in your lines. You also went straight for the most difficult kinds of lines - ones that extend across the entirety of the page, so make sure you also practice the smaller ones.

For your curved lines, there's definitely more wobbling present, indicating that you might be executing these a lot slower - one of the things that is pretty much a given for all beginners is that to draw confidently, they'll often need to move their arm faster in order to not give their brains time to micromanage the movement. This is also important if you're suffering from a slight tremor - additionally, it may help you to loosen your grip on your pen as over-tensing your arm can exacerbate this.

Your ghosted lines show significant wobbling however this clears up a lot in your ghosted planes, indicating you're executing much more confidently and focusing less on accuracy.

Onto your tables of ellipses and it's good to see you've crammed as many of them in there as possible. I did notice that you missed this part of the exercise, where you try to fit lots of ellipses into a wave pattern. Your ellipses here are quite misshapen and wobbly - again, make sure you're executing at a confident pace (speed is not confidence, but it helps at this stage) and ghosting them out.

Ellipses do feel really weird to execute with the shoulder at first and I can see you hit a good pace in your first page of ellipses in planes, while your second page focused a lot more on accuracy. Ensure that you are not focusing on accuracy over confidence, as an inaccurate, confident line is workable while an accurate, wobbly line will always be wobbly. Finally, despite the lingering issues with your ellipses, your funnels are pretty well aligned to the minor axis.

Your first pane of plotted perspective is looking a little odd since your second vanishing point is not on the horizon line. With the exception of three point perspective, all your vanishing points will be placed on the horizon line. The others are well done however you might need a new pen, or to hold it more vertical to the page, given the lines are fading quite a lot.

Next, it feels like you got a little overwhelmed with the rough perspective. This is pretty normal, students tend to see their first box exercise and struggle to think about and plan one line at a time because of all the other considerations and as a result their line confidence suffers significantly. Overall though, you've done a good job keeping your horizontals parallel and verticals perpendicular to the horizon line and your estimation of the convergences aren't too far off the mark - and where it does stray, it does so in expected ways, such as the boxes further from the vanishing point being more inaccurate.

You've done a good job keeping the gaps between your boxes consistent in the rotated boxes, particularly on the front planes. Things got a little more uncertain in the back planes, which robbed you of the chance to leverage the lines of your already drawn boxes in order to estimate where the next one should go. Additionally, your lines got a bit scratchy here, so make sure you're always planning and confidently executing your lines even if you're uncertain about what you're doing. You've managed a fair degree of rotation on some sides of the box, while the outer layers on others tend to follow the vanishing point of the previous box. That's okay though, we don't expect students to nail this or the organic perspective exercise as they're designed to introduce students to a new kind of spatial problem they may not have otherwise considered.

Finally, your organic perspective is showing some much improved line confidence over your previous exercises. The variation in the size of your boxes is creating a nice sense of scale in your compositions - don't be afraid to overlap your boxes though, as this can contribute quite nicely to this sense of depth. There are naturally inconsistencies in the convergences of your boxes however this is something that you will be able to work on in the 250 box challenge.
