Is there anything wrong with my design?

Hi all.

Just finished my first design, and I just want to make sure I haven't done anything stupid or forgotten something (which, knowing me, is inevitable!) Any pointers will be appreciated!

Looks reasonable, although the 1M (gain?) pot will be scratchy, it has DC on it and needs some attention!
And you may find your wet/dry mix pot isn't very effective as the input impedance of the LTP is quite high (about 2Meg). You could easily reduce the LTP grid leak though, if you find this to be the case.
