Default what do you think about this amplifier

Hi I've made my first MOSFET power amplifier, in the output stage I used the IRFP140 with IRFP 9140. The features are these:
rails +/- 21 V unregulated
output rms power 20W into 4ohm
thd 1 khz into 4 ohm 0.0028%
thd 20khz no load 0.002%, 8 ohm 0.03%, 4 ohm 0,064%
signal to noise ratio 97 dB (1W into 4ohm), 108 dB (20W 4ohm)
thd is referred into pure resistive loads.
So how is my amplifier? what do you think about it?
