Looks good to me. I like to dice some carrots in mine sometimes. Occasionally I'll throw in a chunk of vegan butter for richness (or just more olive oil lol).

Whole Thai chilis chopped and fried in your oil before everything else helps give it a nice warming spiciness.

Also tempering your dry spices if you aren't already. I like tomato paste at the end of this too...

What else... Hm, sometimes msg, but I don't really care for it these days.

Also don't ignore the heartier lentils like green - they make great vegetable stews

1kg or dry lentils matched to 150g of curry paste is my lazy dahl. I might add veggies, tofu, coconut cream or whatever is available but that ratio makes a nice spicy dahl from my experience. Be careful with many curry pastes having fish/prawn in them (eg, Mae Ploy Green Curry Paste).

Add some mustard seeds, dried red pepper, asafoetida and give it some tadka. Also consider adding amsul which gives it a nice tangy taste

unconventional but butter makes everything better.
