It is a good effort to write the dark feelings. I can sense that you have a lot within you.
So much so that I can see a few different poems in one piece here.
Allow me to be as honest as I can
I don't come in for corrections in punctuations, spellings and grammar.
I look hard into your writings and I try to get an idea of what you are trying to express.
Expression and feel is there
When I say a few poems mixed into one.
You may be writing about a War
You may be writing about disaster aftermath
or you may be writing about a soccer player
or disaster that comes after virus attack- ashes of dead bodies, concretes that fell into pieces and dusty - turn field to grey. All night in grey,...the last word was plague.
So if your title is about "Field" or "fields". Try to me understand the surrounding. e.g. war, soccer match or after a bomb explosion.
Example if you keep to the "field" on describing a aftermath of a "bomb disaster" it will be quite in line with your present work except without using plague.
l will link "bare foot", field of grey...
As you get up from it, then, there is the Sun that still shines and cast the shadow from the Tree you walk through...
drip in your sense of your past and describe your feelings of lost and desperation...such as this.
Try using the background focus to link back to how you feel
Please pardon me if I am more as honest and direct.
You have potential to write good pieces, and I believe it in you. Already I can sense your "dark" senses.
