A big welcome to BPN. You have come to the right place to learn and grow as a nature photographer.
Your sparrow is well exposed, sharp, good colors in the background.
The perch is a little busy, and you could consider toning down some of the brighter leaves just a sliver, esp the one going up on his chest.
Some might prefer a slightly looser crop if you have some additional canvas. It is always a challenge where to crop an image with a perch like this, but I try to cut off as few of the leaves as possible consistent with my other needs for the comp.
Nice male House Sparrow in full song for sparrow day (although this guy is technically a member of the "weaver finch" family). Colours look great, and nice details. More room would be nice here, especially at left. Although the perch is indeed busy I find that it works well.
