>>4219435I'd recommend learning edge control and looking into tangent control.
Tangent control is just getting your perspective right, a tangent is just an edge. Your values aren't professional, but they're not beginner either you're intermediate. Recommend getting your perspective to intermediate level too.
Remember.
First comes perspective, then value, then colour. Work structurally, go back to line drawings and nail them, overlay your copy with the source material a couple times during your study to make sure you're on track.
I learned so much about tangents and perspective by overlaying my work and no its not cheating.
Keep going anon.
I believe in you.
