Opinions and feedback on my dividend portfolio

I just made a model dividend portfolio today. I have not invested any money into it yet because I wanted to hear other people's opinions first.

I'm looking for a low risk, long term dividend income strategy, reinvesting the dividends over time to compound.

My approach:
Use the dividend kings as my stock universe. Then I just use a checklist (kinda):

Current ratio over 1
Operating margin over 15%
Fcf consistently positive over the years
Positive roe and roa
Debt/equity under 150%

Then I look at product reviews, seekingalpha articles, how long the CEO has been in charge etc. to gauge general sentiment about the company and get a better understanding.

My final portfolio:

DOV
EMR
KO
JNJ
LANC
NDSN
FMCB
FRT
MSA
GWW
BDX
TNC
ABT
NUE
RPM
UBSI
