Dependance - student project

I was taking a stroll with the family at a park and my wife noticed a Mushroom on a tree trunk. I approached it and took this shot. 

I shot this with on a Fujifilm xt3 (33mm Viltrox) with an ISO160/f1.4 and 1/250s. It was a still object so I started to set things on manual until I got the best picture I could. This is all new to me but Justin bridges is an excellent teacher, I hope to revisit all that he mentioned as I continue to practice and benefit from the other classes he has. 

Justin, If you have any pointers on how I could have improved this shot I am all ears.
