For a first map i really liked it, especially the rocks on the last few jumps look cool.
I did think it is a little bit too dark in some places.
Some specific feedback:
jump 5: didnt like the spacing, you basically have to sync in the far corner to squeeze in a wallshot
jump 7: easy telesync cheat (i think you can even clear the gap with just wallshots)
jump 8: my least favorite jump (buttons suck

), ended up just standing on the rim of the wall where the door opens and just wallpogo/wallshots from there.
jump 14: can easily do the jump without the last wall (just sync on ramp)
jump 15: again, i think this jump would be improved by not having a button
but all in all great first map
