Investigated a comment made by ^ClefairyKid about shading with greens over an orange base? This is the result! I ended up with a slightly moldy looking pumpkin (aw), and more muted lighting. Sort of like these pumpkins?
I had to use the more brownish greens instead of the brighter ones to blend with the orange to match my tastes. As well as do a lot of Green then orange then back to green to get the look of a "green" pumpkin.
Since this was just to see what would happen, I only spent half an hour on it. And it definitely could be more refined, but my goal has been accomplished!
I hope this helps, ClefairyKid!
