Funky lefty back at it

Today i pitched 1 inning: 1 lineout to third, 1 groundball to second, a homerun and a centerfield flyball.
My control was good so was my slider, my changeup was staying high in the zone, but i push the ball a little bit.

What flaws do you see on my mechanics? I am a nearly sidearm pitcher.

It is difficult to make any judgements based on a single still picture. Please post some video.

But I will say that mound looks horrible.
