Hi MikeKatar :)
It's looking good!
It looks like you do know what to do and I really like your line.
But I feel like the more you look at the reference your hand become stiff. There's something in your 2 min drawing which is more flowing.
I would recommend to search after the line of action and try to keep you free hand you might have when you do the 2 min drawings.
keep going :)
