Dropping some bodyfat

I have been extremely busy the last few days doing crypto research and studying. I have lost some weight, mostly fat , and while I'm at it I decided I'll try and cut down alot of bodyfat for summer and gain some lean muscle aswell. Here's the 3 week progress I made by just studying, training and maintaing a very mediocre diet.

This was taken 3 weeks ago

And this was taken last night
