Hey there pedro, welcome aboard. I'll be going over your work today so let's get started.

Lines - Your super imposed lines are looking nice. They are confidently drawn from the shoulder with little to no wobble or hesitation and the grouping is nice and tight. Your ghosted lines are also confidently executed for the most part. At the end there are sometimes some hiccups as you try and stop on the point, so try lifting the pen instead of stopping. This is easier than fighting the momentum of your arm as well as giving your lines a nice taper.

Ellipses - Your ellipses are off to a good start. Some might be shaped a little off, but that is getting into nit picky regions. Overall they are shaped nicely with no flat portions or points. In your tables exercise you are doing a good job of keeping your ellipses packed tightly for no ambiguity as well as maintaining consistent shape and orientation within each row. Your ellipses in planes are also looking confident, but the sahpes get a little iffy in a few. I am certainly nitpicking here as your work is overall very solid here. You are hitting the correct points on the planes to make sure they are fit snugly in the bounds and not floating around inside the plane. With your funnels exercise you are doing a pretty good job aligning your minor axes to the funnel axes, but in a trade off your ellipses are suffering a bit while trying to balance alignment of the axes with drawing within the bounds. Overall a good start though.

Rough Perspective - You're doing a good job planning and thinking about each line here. Y our horizontal lines are parallel to the horizon and verticals are perpendicular. Your converging lines are right on track, indicated by your check lines. Your line confidence is great here and you do a good job not redrawing any lines that didn't go 100% as planned.

Rotated Boxes - Once again, great line work here. You do a really nice job with your hatching keeping it neat and uniform to increase visual clarity and aesthetic appeal. In terms of the mechanics of the exercise, you were not rotating your boxes, but instead skewing them and shifting them over. This gif will help you visualize how the boxes are made to rotate, that is by moving the vanishing poitns along the horizontal/vertical axes. You also could have afforded to pack your boxes a little tighter to better leverage adjacent lines as perspective guides, but not a bad start. I also want to point out that even though the corner boxes ended up a little different than the example, you stuck to the perspective that you laid out and drew those boxes accordingly. While they could have been more accurate by packing the back lines closer, you stuck to your frame work and that is to be commended.

Organic Perspective - You can definitely tell you've gone through the lesson once already. Your boxes are looking very solid with a good mind for converging lines. Your compositions are lively and have a lot of scale variation in your boxes to convey fore, mid, and background. To further sell the illusion of three dimensional space you could have overlapped your forms more so they appear to occupy the same space. You definitely started this but could push it more. Your line weight is also looking really nice especially on your very last composition.

So this concludes your lesson 1. It will be marked as complete and your next stop is the 250 box challenge. Keep working on ellipses in your warm ups and things will continue to improve. Keep up the good work and see you nexts time.

Hey Pedro,

I've gone through your lesson 1 exercise and it's really very good.

Your Line quality is so impressive and the strokes are confident. Your superimposed lines are up to the mark and doesn't have too much fraying even though with the curves. The ghosted lines are also very well done.

In ghoting the planes, again your lines are really nice which didn't gone far away from the point or stopped before it.

Your ellipse exercises are showing that you really mastered using shoulder to sketch confidently and consistently.

Not only the plotted perspective is really good but also the rough perspectives are good to mention, lines are really close to the vanishing point.

You did a great job in rotated boxes. You've placed those boxes so nicely that anyone can visualise the half spherical shape that boxes are creating, just by looking once at it.

The boxes in organic perspective are really doing greate work, as the small boxes appear to be so far away and the big ones are too close. Good job here too.

I'm actually really impressed with your work. Your work shows the confidence in you to do that.

By taking a look at your work, I really feel that I should get some advice from you on my own work for the lesson 1, as I've submitted it recently. If you don't mind, can you please critique my exercises?
