/ic/ - Artwork/Critique

I've been watching plenty of lectures and I'm tired of hearing "once you get the construction right, shading is easy". Both are pretty hard, even when I get the construction right, getting this satisfying and nice rendering is so difficult. I get frustrated when I watch these good artists get it done and make it look so effortlessly, but I guess I should use that for motivation.

>alright let's block in the shadows
>looks decent enough, now on to halftones
>oh god why does it look so scratchy
>fuck I thought if you just imagined this a spherical shape it would look good
>fuck Huston you told me this was a boxy shape, why does it look so wrong when I do it?
