hello Krasunir,

welcome to Draw a Box.

Its okay, as long as you are aware of your mistakes and work towards it, you will eventually improve a lot. so lets see what we have got here,

lines : Hmm, good one. Since your lines in both superimposed lines and ghosted lines are arching, i'd like to remind you about drawing from shoulder. It will allow you with more room to work on while drawing from arm gives you smaller room, hence, arching lines as a result. In superimposed lines, the lines shouldnt be fraying on both ends. Since, your lines are fraying on both ends, it shows that you didnt ghost your lines properly, or wasnt careful about it. eitherway that's a mistake. befor drawing a line , ghost them until you feel like you can do it, draw confidently and draw from shoulder. Your lines feel confident, good job.

Ellipses : I wonder what those tiny "x"s are ? i'd suggest you to not add other stuffs that isnt mentioned in the exercises. so about ellipses, i'd only recommend you two thing, ghost and drawing from shoulder. Its good to draw through your circles twice or thrice. ghost and try to snuggly fit your ellipses in the table. i see gaps here and there, Though it might not be possible to totally avoid them, but try your best. Same with your funnel exercise. make sure that your minor axis is cutting your ellipses in symmetrical halves. and that they are snuggly fitted. and aligning to each other.

Boxes : you are supposed to draw the hatching lines with as much precise as you do with lines from lines exercise. mark your every lines with intent . in rough perspspective , I see your lines are breaking, i recommend you to not do that. and also draw your lines confidently as i see some lines are poorly drawn.Apply what you had learnt in previous exercises, here too. dont worry much about perspective for now since you'll be learning about them in next drill. You've done good with rotating box, the boxes are rotating. the only problem here is lines. Your organic boxes are fine too with only problem being lines. over here, it seems as if you are drawing from your wrist and i see one or two "chicken scratching"like lines . always draw from your shoulder nomatter how small or short the line is supposed to be.

My advice for you is , be patient, follow the rules, and practise consistently (ofc without overdoing) . Include these exercises in warmup exercise of a page that will be about 5-10 minutes long.

good luck !
