Hi,
the schematic shows several issues.
The most prominent one is the wrong ´polarity´ of the VAs stage (Q10).
The Collector potential of Q1 would have to be positive, the Base potential of Q10 is negative.
R2 should just be a fixed R of ~100R to 1k .... often it isn´t needed anyway.
A value of 1k is often used as R-part of an RC-lowpass filter with C in a range of 220pF to 1nF.
In that case place R2 ´in front of´, i.e to the left of C2.
Instead of two current mirrors for the long-tailed pair CCS use simple 1-Transistor/1LED current sources with transistor and LED thermally coupled (the CM design/dimensioning appears questionable in itself)
There´s no Miller compensation cap around Q10, nor any other compensation arrangement.
There´s also no bandwidth limiting cap parallel to the feedback R11 ... typical a few dozen pF.
Then there´s no resistor from the feedback point to gnd ... just C3.
You have to add a resistor in series to C3, the value depending on the required gain (Av=1+R11/Rx).
With R11 beeing 22k Rx would probabely fall between 470R and 1k (typical gains ~30dB).
Finally You didn´t draw a V+ connection to the output transistors.
So back to the design board
