Well, I'm no Paganini so there's Little I can say.
What tempo is it to be played at - and if your slurs are phrasing or bowing slurs - like the last beat of bar 1, semiquavers 1 and 2 need the down and up bow marks changing if the slur is grouping the notes under one bow-stroke. Or the up bow sign needs removing altogether.
I'd have marked the bowing with the down bow on the first beat, up bow on the second beat, down bow on the third beat down to the g of the fourth beat and the rest on an up stroke so the player is ready for another up on the chord in bar 2.
Bar 2, I'd leave the player to choose how to play the staccatos - they'd probably do it up bow but might alternate strokes. The last beat on an up stroke...I suspect that's how it would be played if you left out the bow marks........and things.
(Edit] Views will differ about this but unless I want a particular effect, in a piece like this I'd leave the bowing to the player, just indicating what's staccato, accented, spiccato, martelé, if necessary. But it does depend if you want an effect that wouldn't otherwise be natural to the player.
