I like the last image, maybe add a few more whites/highlights on the blacks on the left? Its a bit overshadowed by the background. :D
Hey Anass! You're really pushing this image - it's very rich, very dramatic - but a few adjustments/suggestions. The dark space on the left... I think you need some bounce light to lend some more information to the foreground elements - so imagine there's another diffuse light source just 'outside' of the composition that is highlighting those foreground elements - and use an accent colour - so maybe rich yellow/golden highlights on those spirals? New layer - give it a go!
