What am I doing wrong 😭

My oil paintings are turning out shite at the moment. To be fair, I’ve only been oil panting since last August but I’ve done some pretty good oil paintings that I’m happy with. Recently, they’re just bad! I can’t get the right texture I want, it’s too smooth and blendy and I can’t get the colours right. I think partially, it’s because I’ve bought some very toothy daler and rowney canvases that I haven’t primed enough. I also should probably use palette knives more, currently only using brushes.

Any tips please it’s supposed to be grapes with green bottles of sparkling water, sunflower oil and water bottles.

I’ve already scrubbed it out but I want to know for next time.

Last slide is more what I want it to look like. And yes, I know it takes years to get that good! But I’ve done some better paintings before and idk what I’m doing wrong at the moment 😭
