Not liking the collab; borders are too chunky, bad choice of font and the effects on it, though good positioning. Smudging on the right side doesn't look great either, though the colours are nice. I also think more effects should be added, perhaps a wireframe or two, and 1/2 effect C4D's? The drawing is alright, the lines seem a bit weird in some places, like on the pencil case. I do like the shading on the pens. I'm interested to know: what do you use to draw your drawings? Pencil? Charcoal?
