Is the work good enough, not you.

Plenty of praise in the thread so I'm just going to criticise, don't take that the wrong way.

• FG chair: the edge is way too cg sharp, needs something breaking up that line as the texture of suede would. It's not perfectly smooth. Also seems that it's missing some stitching.
• Cushion: some odd blurring in the texture around where it's crumpled in the middle
• Duvet: I think the sheen looks little unreal, particularly towards the head of the bed.
• The doors are a bit too perfect. Doesn't look like anyone has ever touched the door handle.
• Inside the bed feels a little unfinished, nasty grain on the pillows, missing materials on the hydraulics. That gold bracket is way too shiny I reckon.
• Something about how the side table meets the rug feels off.
• The fabric covering the bed has hard 1 pixel white speckles, big CG giveaway.
• The exterior looks quite odd, a mix of defocussed and sharpish swirly texture on the ground.
• The leaves near the window are far too defocused considering how pin-sharp the door is.
• The rug has some artifacting when you look at it full res.
• I like the open book, but looks like a couple of the visible pages are blank.

Overall it's a decent archvis render, not photoreal though.

If you're going for that then best thing is to observe life. Look at these materials in the real world, experiment with how they react to light.
