I'm sure this will soon be outdated, because I've just started making new Detective L icons, but for now, here are all of my Detective L icons in one place:
Teasers:
1-5
6-10
11-15
16-20
21-25
26-30
31-35
36-40
41-45
46-50
51-55
56-60
62-64
65-66
All of these, except 65 and 66, were posted here before and made in 2019.
Even though those are not new, I still treasure every comment! :) My resource post lists all the makers whose textures and brushes I use.
