ZacD and danshewan are fairly spot-on with their feedback, I reckon.
Overall it's a pretty solid portfolio, I think the site is fine, thumbnails are clear and it all loads fast. A painless browsing experience, which is always nice
The pinkish tree should definitely be cut or heavily re-worked, it's nowhere near the quality of the palm tree.
I agree that the bed looks sharp, but oh well, I guess it's done now. I'd have liked to see more interesting folds in the cloth, and a more subtly rumpled look to the lowpoly instead of just a big flat box essentially. I'd maybe remove the bed for this reason, it just doesn't add anything compared to the other work you show alongside it, in fact it's a little lower quality IMHO.
I'd leave the chopping board in, I think that's a decent quality asset and while it's not a hugely interesting design, it's well executed.
I'd also remove the dead plant "centrepiece" thing, your planter boxes looked way better and showcase the same skills in a more favourable light.
I'd agree with danshewan that your focus should be on highpoly stuff, IMHO that was the weakest part of your folio. In the places you show highpoly work it tends to be competent but not especially amazing or detailed.
The stone face thing, for example, had a fairly poor highpoly, I reckon. It just looked weirdly smooth and stretched, I'm sure you could do a lot better if you spent half a day or so making a new one from a more interesting concept.
I was also a bit confused by the large vase highpoly - while the end asset looked good, the highpoly appeared to be very lowpoly in silhoutte, and the shading was weird around it. Not sure what was going on there.
In general though it's good work and I think with a bit of pruning and reorganisation this portfolio could present a better impression of your work. I also think that if you get some newer stuff in with more interesting / detailed highpoly work (and maybe some nicer renders of that with a cool lighting setup) then that would really round out your portfolio.
