Hello Tsreaper and welcome to drawabox! I'm glad you're enjoying it! Overall youv'e done a pretty good job so you have nothing to worrry about, I want to comment on some things though, so I'll go through them section by section, let's go!:

Starting with your lines you're doing a great job committing to your lines and drawing them confidently through all th e exercises even if they're going to miss then ending dot, which is just what we're looking for!

One important thing is that sometimes I can see a bit of fraying at both ends of the lines, make sure that whenever you draw a line you carefully place the pen at the starting dot so the lines can fray on maximum one end.

Lastly your dots for your lines are a bit too big, try to make them smaller so it's easier to assess the results of the ghosted lines exercises. Other than that, great job planning through all your lines and drawing them cleanly!

Moving onto your ellipses they're confident just like your lines on the lines section regardless of what you said, which is exactly what you're meant to do! The accuracy on them is good as well just like in lines.

It's normal to struggle with them since ellipses are extremely hard, specially the ones you are going to be drawing throughout the other lessonns, but overall you are doing already pretty well! The main issue you are having is that the smaller ellipses get a bit uneven and wobbly, so make sure you focus on drawing those confidently as wekk, using your shoulder and not your wrist, no matter how small the ellipses are.

This is something that happens a little bit on the ellipses on the ghosted planes as well. You might be thinking that the centre of the ellipses is the same as the centre of the planes or that you should modify the elliptical ellipse shape so it touches the contact points, but this is not the case. Ellipses have to be symmetrical and have the same shape regardless of where they are, so the only things you can change is how wide the ellipse is and which position it is in.

Lastly on your funnels sometimes you aren't aligning the ellipses to the minor axis. Make sure you always aim for the ellipses to be cut symmetrically by the middle line even if that means you need to ignore the initial curves. Pay also attention to the angle of the ellipses as well. They have to be cut symmetrically by the line, so they can't be tilted.

Finally in your boxes a few things:

-Lines are still pretty confident in general throughout the box exercises, so I'm glad to see you didn't get confused by the added complexity of the boxes, good job!

-On rough perspective you're making already some good attempts at the perspective lines, but you seem to have a bit of trouble at times keeping height lines perpendicular to the horizon line, and width lines parallel to it. I know it's hard, but make sure you always are aiming for it. You can check if the starting and ending dots are correct or not, and if you find that they aren't you can change them. You can put down as many dots as you want as long as it's before drawing the actual line, so give it a shot! This applies as well on the depth lines, you can ghost towards the vanishing point to check if the lines you are going to draw are correct or not and make corrections based on that, so make sure you give it a try if you haven't already!

-On rotated boxes you've done a great attempt apart from the line issues I mentioned. Most boxes are rotated and all are kept close together, good job! The only thing is that some of your lines are a bit wobbly, so try to keep an eye on that in future attempts. Just like on the other exercises, confidence is more important than accuracy.

-On organic perspective you are also making a good attempt overall with your lines, the main thing is that I think you aren't drawing starting and ending points for all of your lines. If this is the case make sure you do it because it's super important for applying the ghosting method properly.

Remember also that you can add lineweight to the parts of outer lines that overlap with other boxes to clarify which ones are on top and which behind, so give it a try next attempts you have at the exercise!

Lastly you are already doing some good attempts at the perspective of the boxes. Good job! They still have some issues, but that's not a problem as you'll work on them on the box challenge.

Overall like I said you've done a pretty good job so I'll mark this as complete. Pay special attention to always focus on confidence with your lines and to always draw starting and ending dots before drawing any line, which is super important on the box challenge.

From now on you need to do warmups before every session, so don't forget about them! And make sure you ask any questions you might have. Keep up the good work and good luck on the box challenge!
