Though I've workshopped poems in college, this is my first time in the Pig Pen so please give me grace if I do not use the site's best practices in my suggestions - I'm learning

. Overall, I found your imagistic poem enthralling. The image you paint for us with your words is both familiar to an average reader and distinct to the specific speaker. I'm not a fan of your title; "Last Picture" is rather trite and does not capture the uniqueness of this specific experience of "looking at a picture and remembering." I love the verisimilitude of this piece: a poem about a picture; it might be worthwhile to create another layer of artistic reflection in order to really capture this thread in the piece.
I respectfully disagree with the comments of @Achebe in the previous post. I think your "notice for the first time" coupled with the veins and arteries suggests that the speaker is only later recognizing the life-giving, heart-living relationship between the speaker and the one with the sports car. The image of grey laced capillaries coupled with the veins and arteries and "bleed"ing in the last line seem to thread together as a way of emphasizing perhaps the elderliness/poor health of the other person in the poem. If this is what you were looking for, I would suggest that you add maybe a little bit more about wrinkles or other attributes of aging to solidify this hint for the reader. In the last line, I think it might be more effective to connect the berries with the Rowan tree from the previous line. As it stands now, the last line is too disconnected from the rest of the poem. You are creating enough emphasis with the shorter line and the white space before it. It somehow needs to be connected to the rest of the poem - I've offered my edit suggestion in the poem below. Also the grammar in the last sentence was a little off: looming in the background does not refer to "I" the speaker. I added some hyphens to help make the speaker's comment and the looming rowan tree separate in the sentence structure.
Finally, below, I've added some different enjambment and spacing that you might be interested in. But again, Kudos! I really enjoyed this and felt like I was sucked into wrestling with the macro social anxiety of memory and relationship - how we navigate between the discrepancies in our lived experiences/how they shape us presently and the experiences as they are documented - how we let the future imperfect tense inform the way we live with ourselves, our tasks, and one another (Check out Mark Currie's "The Unexpected: Narrative Temporality and the Philosophy of Surprise"). I can't wait to read more from you! Thanks for sharing.
A photo of us taken on a Saturday morning
beside the raised bonnet of your red sports car.
That blue shop rag spilling out of your pocket, rusty
wrench clutched close to your chest, oil in the creases
of your pallid face like grey laced capillaries tracing
your smile. Looming in the background - I notice for the first time -
veins and arteries of the Rowan tree against the sky,
its berries bleed the horizon.
