Op106 Nr1

hello everyone, this is the piece I newly composed, hope you like it.

1. Yeah, this was not meant to be played by one violin. See ilv's comments.
1a. Those left hand pizz's are not impossible, but don't really have to be left hand in the first place.
2. Notation issues here and there. Enharmonic spellings and use of sixteenth - sixteenth rest is unnecessarily specific, unless a note's made about it. Like 132, the slur should not be over both scored instruments. 
3. I kind of wanted more variation in the main theme, like at least one phrase where the whole was extended and grown, rather than dropped off into a new similar section.
4. At 111, make that a tremolo, I think. It sounds super unexciting as 16th notes.
5. I don't know, I quite liked the ending, actually. To compliment you could be more specific about your articulations.
