Hi it_sjustvedant, I hope things are going well with you.

Just for your info, I've been working through Draw-A-Box for about 14 months now, I'm currently on the 250 Cylinder Challenge. I can only speak from my own experience, but I have definitely seen my drawing improve, though it is a very gradual process. Anyway, I'll go through your exercises and see if I can give constructive feedback.

Organic Arrows

Good flow to your arrows here, it's obvious you're drawing from your shoulder. Some of your arrows are falling off the page though, I have this problem as well and it was pointed out in the feedback I received. Try to control the space a bit more, a way that works for me is to place in a rough top and bottom point and try keep within those points. Remember if you're drawing in the top line of your arrow first, the bottom line will extend further below your bottom point. It's just a matter of thinking it through while you're ghosting your lines. Some of the lines in your arrow heads are not connected, this tends to breaks the illusion of form. Using points/dots to plot out the geometry of the arrowhead first can help and then connect them after with your lines. Your hatching is a little rough here, try to slow down a bit with your hatched lines, it's time consuming to do it I know, but you'll be making the most of every moment of your practice time.

Leaves

These look really good, nice flowing lines and convincing forms. Well done on the texture too, nice work. I can see you tried both adding and subtracting the jagged edges, where possible try to add rather than subtract, there's a lot more adding rather than subtracting in the next couple of lessons.

Branches

Good work here. You've broken your curves into more manageable parts and hit most of the edges of your ellipses. What helps for me is varying the degree of the ellipses a bit more just to practice the back and forth flow through 3D space.

Plants

Nice work on the daisy, the texture looks great and the petals feel convincing with those cast shadows. Mushroom looks well, you got those ellipses bang on and texture also looks great.

Good job also on the Hibiscus, just make sure you're always drawing through your forms.The form of the cactus looks good, but it is a little hard to make out whats going on with the cast shadow, Well done on the pitcher plant, that one I remember being pretty challenging. The potato plant looks good, as do your 2 final plants.

Great work overall it_sjustvedant, no hesitation in recommending you move to Lesson 4: Applying Construction to Insects and Arachnids. Good luck on your journey!
