winding the strings into the cheeks of the pegbox affects your sound by dampening string vibrations. like everything else, e.g., nut and bridge groove width.
+1
i see your strings are almost all flat on the peg. that can affect your sound too if, say, the D or A string have any contact with the G string peg. i can't tell for sure, but it looks like they do.
if so, your D and A sustain could benefit from having no contact with the G string peg. it can be tricky to wind them so the A and D string bunch up to a more elevated level and stretch directly to the nut without any contact. doesn't look so nice and neat, but heck, nobody's looking and that's not what counts anyway ("it's all about the sound..."

)...
