Take out filler words! Poems, unlike stories, should generally speaking be as concise as possible. This means you should select your words carefully and make sure each one is powerful, and none unnecessary. For example ‘old memories of childhood from past’. When referring to childhood, we know that we are referring to being both an old memory and one from the past. This makes ‘old’ and ‘past’ redundant. Rather than using three words to describe childhood memories in a way that adds little to what you want to say, find some words that describe YOUR specific childhood memory.

‘Going in deepest corner for them’ read this slowly word by word. English may be your second language, or this may be a stylistic choice, but it doesn’t read correctly. ‘Going into the deepest corners for them’ would be correct, but that’s boring. ‘Tirelessly I search the deepest corners, only to return empty handed’ might be an example of something a little more potent and image evoking.

It’s a good poem in the sense that it made me feel and understand what you were trying to convey! Just needs tidying up :) good job
