I've been trying to decipher this seal from a silkscreen painting by using guoxuedashi and other websites.
I believe the first character is 林. The second looks similar to 鹿 but I have no idea.
The last two characters are difficult to make out, so I've tried to highlight what lines are visible but had to do a lot of guesswork on the last character.
I would appreciate any help with interpreting the seal.
