G'day,
It is very hard to judge a piece without an MP3 but I'll try my best to go off the score your provided.
First things first, as Henry has pointed out, the Dynamics are quite weirdly placed. The Fortississimo's above the declerendo could quite easily confuse a performer, and at times seem contradictory to what you seem to be intending. Also the dims over crescendos are very contradictory, and must be removed.
Secondly, the weird zig-zag lines and pedal marks? underneath the line are NOT symbols that appear in Violin music, unless you've got a specific technique in mind that you have chosen to depict. I'm also going to ask about the second time repeat on the first page which is very out of place with not a repeat bar line or first time repeat in sight.
Lastly, a lot of what you written seems impossible or insanely difficult to play based on what I can see. There are some massive intervalic leaps and falls in quick succession which would require constant shifting up and down the neck and string crossing, which combined with your dynamic markings, would be a massive challenge to play.
This piece needs a lot of work, but I hope my feedback can help you improve it.
Nga Mihi,
