I don't show, and I've actually never done a show trim on a poodle, but I have studied poodle trims so much and what everyone has suggested across the web when critquing show trims!!
I think his rosettes need to be smaller, they're too big. Only need a little off them though, just to tighten them up... Perhaps when he has a fuller mane they will balance better, but for now they look too poofy! lol.
the line where his jacket starts/the shaved butt starts I think needs to move forwards a touch, he looks long and bulky in the body as it is. It needs a touch taken off at the throat, and a touch more at the chest to round it out, possibly a touch off by his elbow too...
Here is my tweaking, I've reduced the rosette size, and drawn in the rough line of the body. Obviously it needs his neck hair to grow in, but you get what I mean about bringing the line forward etc
dunno, like I said I've never actually done the trim myself, so I don't have any real experience on it! I just know what I've studied, and looked at so many pics of the poodles that I think look stunning, and picked apart WHY I think they look stunning!
editing to add the same pic, but with the lines filled in to see more what i mean:
I also realised on edited the pic that by reducing the size of his rosettes the way I did (all around) that when I took the body coat furthur forward then I needed to move the rosettes forward too, so if you DO tighten them up, take more off the back of them than the front to balance it! lol.
