Very hard to say given that it won't have cured yet and I don't know what look you were after. However, there are no smears on the bricks, which is good. Very easy to smear lime on the brick faces if you damp down the bricks and then push in the mortar, so whoever did it was careful not to let that happen. It looks as good as the pointing I have done, though I prefer a slightly more 'churn brushed' look to get a bit more aggregate exposure, but that mightn't work so well with those bricks. I also prefer it a bit more flush with the brick, but that might just be me. The only thing I've found (with putty mortar pointing), is that you have to mist spray it fairly frequently for a few days in order for it to cure properly and not get friable. You should be able to close any little cracks (like the one in the second photo) by pushing on it with your finger.
Agreed with jamest, it could be slightly more flush to the brick-faces, and I also like the brushed / polished aggregate look but overall it looks pretty decent to me personally. If it's still drying out it will probably get lighter in colour over the coming days as well, which I think looks good as a contrast to the masonry.
Put another way, I've certainly seen MUCH worse out there. Not so much with lime, but definitely with nasty cement strap-pointing, or really patchy, discontinuous cemented mortar joints and stuff that you can tell is just perched on the surface of the joint and hasn't actually been pressed deep back into the joint.
Thanks for the inputs; maybe I’m a heathen but I quite like the slightly recessed mortar. It’s definitely still curing so should lighten up a bit. Aesthetics aside I guess the proof is in how it holds up over time
The job looks fine to me. There's only so much you can do with a flush joint. A slight recess can improve the appearance with older chipped bricks, or new tumbled ones. Key points with a lime mortar repointing job are raking out deep enough, cleaning out and damping down the brickwork, and mixing up the mortar properly.
