Lovely Tali. It’s great to draw from life. And difficult! The vase is good. I like the pink hues.
A few suggestions
Check the level of background, in this case the table, with a ruler
Look at a grey scale version of the painting and adjust where needed – look at the leaves coing out of the vase in contrast to the one’s nearest to the light
Decide on your focal point and then paint that flower with extra detailing – that will help with the depth
Here is your grey scale version

Good work, well done! As noted above, a little more difference in values would really make it.

This is very nice, Tali.

Since you mentioned depth, I would suggest some darker green in among the stems, where they would be in shadow. But perhaps, after all, that’s not what this lovely cheerful picture is about.

Thanks E-J and Rich,
I agree that more contrast is needed, both with adding dark greens and adding contrast to the BG as mentioned before. Perhaps I’ll get to that one day, right now I think I might start other, more interesting things
I did this drawing more as an exercise to try OPs on top of neocolor II on canvas and my conclusion is that it works fabulously and helps save both the OP sticks and the texture of the canvas. So all in all I’m happy.
Thanks for the comments.

It’s completely up to the artist’s choice how they want to push the painting or not.

Imho, I love the charm of the first beginnings. Not every painting has to be realistic, with the boxes checked (values, light, composition, etc.) If you like it, than leave it.

It’s got a very nice charm that I’d love to look at on my wall, anyway.
