Think in masses, not leaves
The biggest mistake is drawing individual leaves. Instead, see a tree as a few clumps of foliage catching light, sitting on a branch structure. Get the big masses and their light/shadow right and it reads as a tree instantly — detail is secondary.
1. Build the trunk and branches
Start with the trunk, tapering as it rises, then branches that get thinner and split as they reach out and up. Branches alternate and reach toward light. Even hidden branches inform where foliage clumps sit. Use a textured brush for bark.
2. Block the foliage masses
Block the overall silhouette of the canopy as a few overlapping clumps, not one round blob. Leave sky holes (gaps you can see through) — they make foliage believable. Use a foliage brush from the nature category; see the best free nature brushes.
3. Light the clumps
Pick a light direction. Shade each foliage clump like a rounded form — light on top toward the sun, shadow underneath. Three values is enough: shadow, mid, light. This is what turns flat green into a dimensional canopy.
4. Add highlights and detail
On the lit side, dab brighter highlight leaves with a foliage brush; keep the shadow side simpler. A few individual leaves on the silhouette edges read as detail without drawing them all. Don't over-detail the shadow areas.
5. Color the foliage
Trees are rarely one green — vary warmer greens in light, cooler/darker in shadow, with hints of yellow or red. A flat single green is the giveaway of a beginner tree. Color on layers or with Alpha Lock over your value blocks.
Different tree types
- Deciduous — rounded, billowing clumps.
- Pine/conifer — layered triangular tiers drooping outward.
- Palm — long fronds radiating from the top.
- Distant trees — simpler, lighter, just a lit silhouette (see atmospheric perspective).
